Microsoft accounts being an absolute pain in the ass to set up and manage, and the new launcher being aggressively terrible, are salt in the wound even if you finally gave in and migrated your account.

Also, good luck running Microsoft’s Minecraft launcher on a kid’s computer with allowlist-only internet access. It connects to like 20 apparently-random IP addresses every time it launches, will not work if any of them fails, and the pool of addresses is evidently huge. I never did find anything like a list of IP blocks to allow. Maybe they keep a file with them all in it somewhere, never looked, but I have a feeling they hit one address that gives them their list of the others for each session, and only that list, like if I had to bet on it I’d go with that (if they had a larger list, why aren’t they re-trying with different addresses when one fails?). I guess they just don’t care about that use case. (“Why don’t parents just police their kids’ internet access?” yeah look some of us really try but shit like this is everywhere and makes it stupidly difficult)
