Probably Google just wants to block them not because they care about the creators but because it's costing them bandwidth money.

From the new agreement that they had with warner bros for creating closed captions, it looks like Google is also stealing the subs for training, they had direct access

It just sucks that someone pays hundreds of dollars to have a human create subs for a show, then that is used without credit or permission for training a model (actually whisper accidentally credits moments of silence with the name of the subbing groups used for training)
