Given how things work, they should have created another “brand” just for the spotify breach (e.g. Audio Hub). Annas Archive was just going so well…

Nah. AA themselves say they don’t think it is due to Spotify. And it would be too quick, they say they were kicked based on a legal request, hardly something you expect to be carried out in, what, two weeks at most?

Book publishers are unlikely to be any less ruthless than Spotify. Remember how they wanted to fuck over Internet Archive (and partly succeeded). This is more likely to be their doing.
