Not your main point, but in the Berkeley videos case I blame, well, Berkeley. They could have taken the videos offline temporarily, worked on transcribing them, and brought them back gradually (they have the resources or, if they’re too cheap, could have resorted to crowdsourcing). Taking that wealth of knowledge offline so abruptly, and with no plan to ever bring it back, is really a disgrace. The videos live on thanks to Archive Team, but they’re not as easy to discover.
