Was it really Microsoft or was it Mojang? There were two account transitions, and in my experience, most customers use Microsofts name, but are complaining about the first (Mojang, not Microsoft) transition.

It doesn't matter. An acquiring company acquires the 'sins of the father' as well. A paying customer had their account wiped out is the bottom line.

You're telling me people lost access to their Minecraft accounts due to a transition BEFORE Microsoft owned it? I had no idea.
