Hey there. We just wanted to chime in that you can avoid the account closure by logging into your account within the 30 days (since receiving the email pictured) and selecting the Cancel Account Closure link contained in the email. We certainly do not want you to lose access to your games or account so if you have any difficulties logging in then please create a support case with us. >> ubisoft.com/help
You don't own it, though. The same can happen on Steam, though they're obviously not that shitty. The only store that lets you "own" games is GOG, that's why you won't find new games by shitty companies there.
