This may also be a financial decision. Bandcamp is not a huge player compared to Spotify, Google, or Apple. Deezer said more than a third of new music uploads are GenAI now. If AI slop starts outnumbering real musicians' uploads 10 to 1, 100 to 1, or 1000 to one, which doesn't seem so far out there given the complete lack of talent, effort, or experience required to generate it, how would a site like Bandcamp pay for storing and processing all that data? They may have no choice but more rigorous curation.

Also, it's kind of antithetical to the purpose of Bandcamp. As you say, a place where anyone can publish music - but that's true for Spotify et al. these days, too. Bandcamp was always about a more direct connection to the artists, so it makes sense that they want their site to be about actual flesh-and-blood artists who have put sweat into their work.
