“SpaceX must swiftly and explicitly separate itself from Elon’s personal brand,” sounds a bit like cancel Elon.
Having seen the full text of the letter it has a bit "But for all our technical achievements, SpaceX fails to apply these principles to the promotion of diversity, equity, and inclusion with equal priority across the company, resulting in a workplace culture that remains firmly rooted in the status quo." Which sounds quite cancel culture.
