While that's true, it clearly worked and massive channels used it. So why is YouTube's avoiding any responsibility and trying to kill it as quickly and silently as possible? Like, I get that sometimes you'll have to drop support for things (even things you unofficially support), 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 a heads up for that or even help them out.

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. So it doesn't even make sense to take that risk from what we know.

More like unofficially supported. The fact that they worked points to the fact that they were quite literally supported.

YT is throwing out the baby with the bathwater

Those styling option sure sound like something SSA subs could do...Wonder why that wasnt used.
