Microsoft stole two of my accounts.
I bought Minecraft in the alpha days when all you needed was a username and password. At some point they mandated an email in the years I wasn't playing and later found out I could no longer sign in.
I bought a new "copy" and lost it because I didn't migrate to a Microsoft account. I didn't migrate because I assumed it was just a scare tactic and I wasn't playing at the time anyway. When I later wanted to play they stopped allowing me to log in.
When I look at the top selling games[1] and see Minecraft in second place with 400 million, I wonder how many of those are the same people buying it again. I'm sure nobody bought Super Mario because it would stop letting them sign in to play offline.
