While that’s true, why is YouTube’s response to kill it as quickly and silently as possible? Like, I get that sometimes you’ll have to drop support for things, but there should be a phase out period during which people can either backup and re-upload videos with those captions to preserve them. They could and should honestly provide support for that.

Now they are literally decimating people’s hard work and on top of that pissing off actual partners. Not saying it will be successful, but cutting into people’s business like that is the kind of thing you can get sued over.
