Assuming they go through with this:

Some of these videos are so short that I think we'll see an increase in browser extensions that let you download the video directly. They actually already exist, but I think they'll become more popular.

Content creators might also upload to other sites (aside from YouTube), which is great because YT needs more competition and doesn't deserve to exist after all they've done.

A possible compromise might be that adblock users will be limited to lower res videos, maybe 480p (then 720p in the future). If they're worried about costs (lol), then it makes sense that high res videos cost more money and need to be funded by ad revenue.

Maybe ad-blockers will develop a workaround.
