That’s a self fulfilling cycle. If more institutions and organisation left and made a public statement of not wanting to be associated with fascism, then it would push another bunch to have to defend why they didn’t think nazi salutes were a problem, and they’d leave too.

Whether it makes enough of a wave to push major groups to leave is a question of public pressure, but that public pressure is expressed through “costly signalling” that show organisations have values and are willing to take a hit to live by them. And non-profits are exactly the groups who can afford to take a symbolic stand, and make things more difficult for those that remain.
