This is such a non issue.

Literally from the link that was posted

We may also close long-term inactive accounts to maintain our database. You will be notified by email if we begin the process of closing your inactive account.

If your account was flagged as inactive and you would like to keep using it, you can cancel the closure of your Ubisoft account.

Did you even read it.

They are not closing your account randomly they’re closing old accounts as is required by law, you are wand that this will occur and given time to log in and prevent it from happening.

And there isn’t anywhere on that page where they say they will delete your old game so I don’t know why that bit comes from.
