I don’t know that this qualifies as enshitification… on one hand, the author created something that scratched his own itch, shared it, and now it’s become a tool that he wishes to steward into a way where he can make money.
I don’t know that these are terrible things inherently, it kind of depends if he wishes to extract as money as possible from his users by any means necessary or if he’s truly trying to scale it so it can help people. All we have is this article and infinite speculation.
I personally didn’t find herdr useful, so I have no stake in the direction of what the author decides to do with herdr.
