It really depends alot on the situation, I do agree however, when you compare Open Source and Free Software, Open Source seems to be designed to be exploitative which is why it is supported by large companies. As you said the AGPL is really the only way to go as it means you get access to every modification a large company makes to your software, which is why the Linux kernel (albeit GPLv2, which is also a good copyleft license) has become such a big project, running on the phone I’m typing this on and the servers our Lemmy instances are on.
It’s probably not the answer to everything and FUTO are trying to fix this (probably the wrong way though) but AGPL is really the best license to avoid exploitation, that way if they use it, you get in return more source code.
