If you want to get a better picture of the situation, read up on the licenses and what they do, specifically the term "copyleft".

I make this point because it causes confusion. Saying "my OSS project is being run by others for money and I get none of it" is confusing, as it uses the supertype. Using the subtype is clearer, and even self-explanatory: "my project I licenced so others can make money from it while giving me none is being run by others to make money from it and I get none".

That may be a bad situation, but at least the reasons are now clear.

No! That's a gross misrepresentation of what open sourcing is. It's the offer of a deal. You publish the source code and in return for looking at it and using it for sth, I have obligations. Like attribution and licensing requirements regarding derived works.

You can read licensed code, learn from it, and then write your own code derived from that learning, without having committed a copyright violation.

You can also read licensed code, directly copy paste it into your codebase, and still not have committed a copyright violation, as long as you did so in a way that constituted fair use (which copy-pasting snippets certainly would).

There’s no copyright issue here at all, and rationally speaking there aren’t any legitimate misuse of open source concerns either. If these people were honest they’d just admit to feeling threatened by AI, but nobody would care about that, so they just try to manufacture some fake moral panic.
