YouTube SRV3 subtitles reportedly being disabled, users report custom captions no longer working
(kbin.melroy.org)
YouTube appears to be cracking down on SRV3 subtitle files, disabling new uploads and deleting existing custom captions from major channels including Hololive, Dream.
Personally I think it would be economically feasible for them, probably not convenient to switch because they would lose a lot of visibility, but having a mirror site (and, especially, a mirror place to superchat dodging Youtube's cut) would be a genius move with their current market share, imo.
It depends where the majority of revenue for them comes from, superchats or YTads, honestly I don't know. If it's ads, it wouldn't be a good idea to abandon YouTube (then again, I wouldn't mind ads on 'CoverTube' if they weren't too many)
I heavily doubt it's ads, channels whose majority of the audience mainly watches livestreams usually get very little from them. And they make a TON of money from superchats (and membership!) compared to the average streamer, so I'd assume the divide is even bigger.
The main reason why abandoning Youtube as a whole might be detrimental is for the visibility. You get a lot less new users if you spin a new platform, it's a move you can afford to make only if you know your current audience is enough to be self-sustainable.
