Not only that, if this isn't cancel culture and/or this needs to serve as the one exception, would we not also be required to go for the full nuclear option and stop using not only the GPL family of licenses, but all software that refuses to migrate off said licenses? Merely asking the FSF board to stand down is a meaningless gesture, as the entire foundation would need to cease to exist as it shall always be under rms's shadow.
Cancel culture is a dangerous thing, and shouldn't be tolerated in any liberal community that intends to protect the rights of individuals using ideals such as Freedom and Free Speech.
Note: Although I dislike how RMS conducts himself in person from time to time, that isn't a good reason to shove him under the bus. He makes arguments with zero tact, but does not make arguments made in bad faith. He clearly is somewhere on the Autism spectrum, and most likely was never diagnosed due to proper diagnosis not being invented until his 20s, and proper treatment not being invented until his 40s. The community needs to make sure we don't become some violent revolution that turns around and eats our own because its convenient.
