I do not believe this would address the root issue, which is not "how to put pressure on Google to do less evil".

The challenge is to moderate a popular service where any user can upload content that many actors will try to abuse.

Even putting aside that YouTube is partly supported by ads, there is no known solution as far as I know, short of turning YouTube into an old fashioned TV channel with only a few vetted content creators allowed to upload.

It would be sufficient to notify banned uploaders what rule(s) they broke and add a human-powered appeal process. With the former, the latter will be relatively cheap as reviewers and uploaders could address the specific issue.

With sufficiently complex systems to detect fraud, such as AI or that involve constraint optimisers, it is not always doable to isolate a single, clear parameter that is responsible for the data to be flagged. This is an issue also for them (source: been working on several complex rule based systems that exhibited this very problem).

As for the human powered appeal process, how to design it so that it is not spammed/abused as easily as the upload?

It's easy to explain everything away because of evil corporation, but those are also actual technical issues.
