I’m maybe daft but AGPLv3 doesnt prevent $Evilcorp from using it, they just need to share any modifications or forks they made?
Only if they provide the software or software as a service. Then I suspect it's good enough if the modifications or forks made are shared internally if software is used only internally, but on the other hand I'm not a lawyer.
This is the point. They can use and modify it, but they also have to share their modifications, i.e., help its development. Yet most megacorps never even touch this license.
And at this point, it appears running code through an LLM to translate it eliminates copyright (and thus the licence), so $Anycorp can use it.
Our stuff is AGPL3 licenced and if this present trend continues we might just switch to MIT so at least the little guys can take advantage of it the way the big guys can.
