Richard Stallman was paid to give a talk at Microsoft. https://stallman.org/articles/microsoft-talk.html I don't know what point you're all trying to make: it's possible to accept money from the bad guys without that compromising your future actions. Just because the Linux Foundation hasn't managed it, that doesn't mean the Software Freedom Conservancy can't.
For one, I cannot examine all signatories of the Stallman cancellation petition here. Then, given the cancel and defamation happiness of the PSF, this is an excellent example for double standards.
