Nowhere on the linked page at least does it say that it was due to cost. It would seem more likely to me that it was a question of nobody wanting to bother standing up for the videos. If nobody wants to take the fight, the default judgement becomes to take it down.

Yet this feels very harrison bergeron to me. To handicap those with ability so we all can be at the same level.
