Q for astronomy people: This is tracking the sky movement as it takes the pictures right? Also, with the atmosphere moving, is there a limit of how large the telescope can be and take photos from earth, before it can't get more quality?

The mirror coating timelapse video is pretty awesome https://www.youtube.com/watch?v=Gg9UPS7ndRA

Is there a figure somewhere on how many TB of images this will produce per day when running in automated sky survey mode?

> The vast archive, growing by 20 terabytes each night, will after 1 year contain more optical astronomy data than that produced by all previous telescopes combined.

Has this not been affected by USA science cuts?

No, but its space-based counterpart was cancelled (the 2.4 meter wide-field survey telescope).

It's been over 10 years since they started. I don't know what the funding details are, but overall this is not really working on a scale that 5 months would change.
If you're just here looking at the HN comments: check out the article. It's really well-written and has a bunch of nice visualizations if you like astronomy things.
