Similar for me. I was very suspicious at first that the first message was a Scam and if I clicked I would blow up the website or something tricksy. Then with the second message I thought it might be customized to test my chosen virtue, "resisting social pressure", so I didn't click it.

People in MIRI/CFAR/LessWrong ~actively resisted the idea of a marketing push optimized more along dimensions of mass persuadability, for better or worse. One reason is that there is inertia once you've built a mass movement with MoPs who can't dialogue like on this site. My straw model is they think "we just need to produce technical insights and communicate them" and other comms work is an opportunity cost or creates/incentivizes some kind of epistemic trap.

And this is the exact type of statement where I would expect this coincidence to pop up. Both are a reasonable number of days for bureaucracy to take, the large discrepancy between them is required for the complaint in the tweet to happen in the first place, and I would expect the number of days to be very specific rather than a round number.

I agree with this. Although I will note people are claiming it actually took 56 (IIRC) days for them to get back to him.

I think it's an entirely sensible inference in the world where it is true that it was intentional, albeit a highly reductive description of the actual psychological reality of someone who holds those beliefs enough to output such symbols. In that world, he could also be paying lipservice to pander or be trolling.

group homes (in adulthood as a long term situation)

People living together in group homes (as extended families) used to be the norm? The weird thing is how isolated and individualist we've become. I would argue that group houses where individual adults join up together are preserving some aspect of traditional social arrangement where people live closely, but maybe you would argue that this is not the same as an extended family or the lifelong kinship networks of a village.
