AFAIK the copyright scan only happens on files shared from certain types of Drive accounts, the assumption presumably being that while Google doesn't know or care if you have rights to possess data, they can be reasonably sure you wouldn't be using Drive links as the means of distributing many well-known files (video, music, software, mostly) if you had rights to do so.
How far Artificial Stupidity runs into the weeds from that basically sound beginning appears to be "still farther."
FYI Drive also does scans (configurable on business accounts) for data such as likely accidental PII disclosures on shared data, and anti-malware checks on at least Windows and Mac executables, installers, and dmgs.
What is the best in class cloud drive software which doesn't do this? I feel like Dropbox is a bit more selective, but without going into the Megas of the world, there doesn't seem to be a good file share with solid end-user desktop sync.
Honestly, when I read a few months ago that Google was scanning Drive for illegal files (probably only when shared but unconfirmed) I decided to back out of Drive, and I figured that all the other big/reputable players are doing it too so I've gone back to a portable hard drive.
Maybe B2? It's not something I have to looked into extensively. My needs for sharing data from GDrive are limited and if there is data I don't feel like google automation getting at I have it encrypted via rclone mounts.
Just tried that, and I get a "request a review" link. Interesting.

Clicking on it, though, gives no joy:
