The solution is to use AGPLv3.

I’m maybe daft but AGPLv3 doesnt prevent $Evilcorp from using it, they just need to share any modifications or forks they made?

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.

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.

> if software is used only internally

Internal users are still users tho. They are entitled to see source code and license allows them to share it with the rest if of the world.

Employers might argue that such internal use and distribution would fall under the “exclusively under your behalf” clause in the GPLv3, which is inherited by the AGPLv3.

Oh, I guess it would. Ignore me.

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.
