Maybe they just think it's more effort than it's worth to host controversial content. If people file complaints about the videos, they'll have to assign someone to determine if the content is credible, and have to deal with the risk of not censoring some videos that should be censored, or censoring some videos that shouldn't be censored. The low-effort option is to just shut it all down and be opaque and hand-wavy about the reasons. Which is to say that they're betting that few people actually care enough about this stuff enough that it would cost them revenue.
