Open source licensing isn't a party, it's a business decision you make as a participant in the intellectual property economy. If you make a stupid and/or uninformed decision, you're opening yourself up to exploitation. It is victim blaming because this situation is entirely the victim's fault.

I don't even know what you mean by "horizontal aggression", and your comment about peasants makes no sense in this context. How does advocating that people be informed and use appropriate licenses count as in-fighting, or beneficial to big tech companies? If anything it's literally the opposite.
