For Minecraft they inherited a gigantic userbase from Mojang and then made it 10x harder to add new users.

I did it for my kids to have accounts and I do not understand how anyone who hasn't built a Gentoo from Stage 1 has a prayer of managing to buy Minecraft Java Edition for their kid, and making it actually work.

Then you've got the hell of overlapping permissions systems on the console and the Microsoft account, to get any amount of online play working on a console if you also get Bedrock. On the Playstation, especially, the error messages also love to not tell you which of the two systems is blocking you, so you get to guess. And Microsoft's site for managing those permissions is so confusingly-laid-out that even after doing it three times in a row I still felt lost on it.

I never did solve the problem of getting Minecraft Java Edition to run on a kid's MacBook with allowlist-only Web access. It wants to contact ten or so apparently-randomly-selected-from-an-enormous-pool IP addresses on every launch. I never did find documentation of which IP blocks I needed to allow, and couldn't guess at it from the IPs themselves. If they'd just used domain names... I must have manually hit "allow" a bunch of times during twenty separate launches, and it was still presenting me the same number of prompts every time, because there was no overlap in the IPs contacted (adding insult to injury is that I'm sure all but at-most two of these were spyware horse-shit that had no actual generously-necessary role in running the software, but it'd fail if it couldn't reach them)
