Maybe, maybe. I agree with a cousin comment, that this is more of a canary than anything. I posted the whole of his letter at the top level, in large part to examine how much of his letter you're fixating on. Turns out, it's a very small part -- and he spends equal time on other public notices, and you've left that point unaddressed, so I'll expand on it.

In grief, one's loneliness is deafening, even when surrounded by loved ones. When this internal loneliness is accompanied by external loneliness, the pain is amplified to a degree that I cannot express in words. To see extensive public adulation of minor accomplishments, the lack of compassion is drawn out in painful contrast. All this serves an example of "toxic positivity" -- of which he exemplifies through a clear anecdote -- which is one of several complaints he has about the organization.
