Privacy doesn't mean anything anymore, anonymity does

Sadly, everybody using a browser from a massive ad company and an idp (not to mention a company with an interest in crawling the entire web for AI at the same time site owners are dealing with better scrapers) means the entire web will be login-only over time.

What scares me is that the more privacy oriented you are, the easier you are to fingerprint. At what point does privacy mean blending in with the crowd and not sticking out?

You're thinking about browser fingerprinting (client-side), but my post is about service-level anonymity (server-side).
Browser fingerprinting: "Your unique combination of extensions/settings makes you identifiable among other users."
Service anonymity: "There are no other users to compare you against because we don't collect identifying data."
When you sign up with just a random 32-char string, there's nothing to fingerprint. No email to correlate. No IP logs to analyze. No usage patterns to build a profile from.
Fingerprinting matters when services collect behavioral data. We architected our way out of having that data to begin with.

There's STILL a browser fingerprint, IP logs to analyze, usage patterns to build a profile from. You may claim you don't collect it, but users need to take your word for it. This is just pseudonymity, which (as many BTC users found out) only gets you halfway there. Real anonymity is way harder, often impossible.
Don't get me wrong, it's good to see organisations that care about privacy and in fact this blog post encouraged me to consider your services in the future. We have some use cases for that at work.
Though by using cloudflare you're NOT putting your money where your mouth is.

I was going to say making the platform open source might solve this problem, but then users would have to trust that we are actually running the open source version and not some fork with logging and tracking. This would be an interesting problem / paradox to try to crack.
But you are 100% right, I will look into alternatives for Cloudflare, which we are using because it seems like the cloud hosting industry LOVES to DDoS new players.

Any business that isn’t willing to be as anonymous as Mullvad, I assume has a compromised business model that I don’t really like. Assuming there aren’t obvious reasons for needing the data, like tax filing, or various regulatory requirements.
I don’t understand why any company would want the liability of holding on to any personal data if it wasn’t vital to the operations of the business, considering all the data breaches we’ve seen over the past decade or so. It also means they can avoid all the lawyers writing complicated and confusing privacy policies, or cookie approval pop-ups.

They're OK with the liability exactly because of this very sentence. As you said, there's so many data breaches... so where are the company-ending fines and managers/execs going to prison?

GDPR has fines:
Up to EUR 10,000,000 or up to 2% of the total worldwide annual turnover of the preceding financial year, whichever is higher; applies to infringements such as controller and processor obligations, security of processing, record-keeping, and breach notification duties.
Up to EUR 20,000,000 or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher; applies to infringements of basic principles for processing, data subjects’ rights, and unlawful transfers of personal data to third countries or international organisations.

Here in Japan the government cracks down on it hard. There are fines for every n users exposed and in extreme cases a company can be forced to stop trading for a period of days or weeks. Companies are so scared of this happening to them that a significant portion of orientation for new employees is spent on it. I don't have stats on how effective it is, but I do know that the public is less willing to accept it as they tend to elsewhere.

Is this true? KADOKAWA had a massive hack last year that leaked a large amount of sensitive user data and as far as I know has faced no legal repercussions. Obviously they took a decent financial and reputational hit, but that was just an effect of the hack itself, not any government intervention.

Wow good for them. I wish we took it that seriously in North America.

Maybe ironically - just going on the title because I can't read the rest as a result - it's behind a cloudflare gate.

tl;dr “Privacy” = the data is private i.e. only on your devices. Or if the raw data is public but encrypted and the key is private, I think that qualifies.
“Anonymity” = the data is public but not linked to its owner’s identity.
If you’re sharing your data with a website (e.g. storing it unencrypted), but they promise not to leak it, the data is only “private” between you and them…which doesn’t mean much, because they may not (and sometimes cannot) keep that promise. But if the website doesn’t attribute the data except to a randomly-generated identifier (or e.g. RSA public key), the data is anonymous. That’s the article.
Although a server does provide real privacy if it stores user data encrypted and doesn’t store the key, and you can verify this if you have the client’s unobfuscated source.
Also note that anonymity is less secure than privacy because the information provides clues to the owner. e.g. if it’s a detailed report on a niche topic with a specific bias and one person is known to be super interested in that topic with that bias, or if it contains parts of the owner’s PII. But it’s much better than nothing.

I would much rather have privacy with e2e encryption than have anonymity. The way that works is a direct connection between two parties without use of a central server, like webRTC.

This was authored using an LLM, wasn't it. The style is unmistakable. Stop wasting our time with this slop.

Here's the thing. It's not just x, it's hyperbole y. Hyperbole. Y.

There is no such thing as anonymity. With the number of bits required to ID a person and the fact that you are leaking such bits all the time you can simply forget about anonymity.
Many people online seem to think that they are anonymous and so were emboldened to do stuff that they might not have done if they had realized this. They continued to feel extremely good at this right up until the knock on the door.
