This scam of taking over non-profits from the founders is super common these days. Look at how they tried to kick Stallman out of the free software foundation by throwing together a bunch of allegations. It failed, but it worked for kicking Aubrey De Grey out of SENS after they received 20 million and now kicking out the founder of Project Veritas. The donors don't support any of these actions, because they care about the mission and not who was offended by a few sentences in an email sent decades ago, but the cliques on the boards do it anyway and ultimately trash the reputation and fundraising capabilities of the institution they are claiming to save.
