I have a feeling it'll probably due a great deal of harm to the idea of Anti-adblock being "actually effective". Up until now it's only really been used by a handful of News, file download, and... Mature content... sites. Places with smaller userbases and less traffic where the effort for bypassing them is lower or just not discussed due to the small size or nature of the site.

It's not really the case here though. So in one way or another this is going to fail.

I would definitely recommend people start backing up YouTube videos from older creators because I imagine that after this they'll be looking to reduce costs and that likely means purging inactive channels or channels that cost more than they make.
