ACA began to promote and fund (in the way of grants) rides and gatherings for narrow demographics. Perhaps one way of 'celebrating diversity', but it's the opposite of inclusivity.
Or they saw that their user base of older white guys like me was rapidly dwindling, realized that they'd missed the bus re bikepacking (whose main online presence, as pointed out earlier in this thread, promotes diversity much more aggressively and yet is thriving), and figured they might as well go down fighting.
