> YouTube says that because "many of you rely on community captions, YouTube will be covering the cost of a 6 month subscription of Amara.org for all creators who have used the Community Contribution feature for at least 3 videos in the last 60 days."
That arguably points out 2 things. (1) they aren't abandoning disabled people and (2) they're probably not lying about the feature not being used since if it was being used this offer would cost $$$$$$$$$
It sounds like nothing really changed. You can still contribute subtitles to a channel, one of the few that actually uses them, and the channel creator can still attach them to videos. All that changed is the interface to edit is no longer in youtube. Choose any of 1000s other ways, send the creator your subtitles, creator can attach them to video.
