I'm not SublimeText user neither. IMO the problem was really #2 and #3. It's perfectly fine to switch the license model between major versions, and it might even be fine between minor updates as long as the committed maintenance period elapsed. Doesn't matter which method was chosen, at least prompt the user before installing the update that a new license is required to continue installation. If the user opt to not continuing, then the upgrade should be cancelled, auto-update should be disabled permanently and no changes should be make to the users system.

Sublime's behavior was deceptive and invasive, their users have all the reasons to grudge.
