One and only account (Mojang) that I can think of that I lost because it got taken over, and I couldn’t get support to help fix it (something about “go make another Mojang account”?)… and since I don’t really get the migration process they did or final outcome, it’s more of a “oh well losing that sucks”.
This situation was a lot more common than people might think. If you bought the game before Notch introduced the EULA (late 2011 if memory serves), what they did was also probably illegal, since they didn’t have the legal boilerplate in place that would allow them to brick the game the way that they did. There was a streamer trying to start a class action over it a few years ago, but I don’t think anything ever came of it.
What they did was illegal, and you absolutely can (and are encouraged to do so by Microsoft) sue them in small claims court for your Minecraft account back.

Source? It seems that if they wanted people to get their lost accounts back, there's more efficient, less expensive ways of doing it?
"Encourage" may be a strong word, but it's specifically outlined in the Microsoft Services Agreement:
