OK, ok you talked me out of even a day dream. I do remember hearing about people trying to make changes at... coca cola (?) doing shareholder action trying to get them to stop stealing water from people or something like that and it basically didn't work.

Agree wrt stock market etc. I mean the whole thing is based around the workers at the companies being fucked and you are just trying to get in and exploit them a bit extra. That is your best case scenario as an "investor". I was kind of filling in an implied worker coop thing I guess. Anyway this kind of intervention has been attempted in various venues for decades and never works as far as I know. Sometimes worker take over and worker buy outs do work and I guess that is more what I am really thinking of. I am thinking of the 3rd party devs, mods and users as workers. But you are right they never succceeed to take over via sneaky means; only directly.
