Do you know how many they've closed so far? I couldn't find anything to quantify that. This definitely concerns me if it's more than some PR error—I have a number of games directly thru Ubi.
Seems to be a definite problem with this strategy tho if it's real, for people whose Ubi account email address has lapsed—eg ISP closed down.
The article didn't say. I think they requested more info from Ubi.
One thing that bothers me is that Ubi only has so many games. I can easily see myself going years without playing an Ubisoft game. If I were an Assassin's Creed only player, well, it's been 3 years since the last Assassin's Creed, and what if I want to wait till the new one goes on a decent sale before I buy it? That could total 4 or 5 years. No idea how long you have to be inactive before they delete your account, though. Something like 10 years would be less threatening than 5, but it's just the concept that is irritating.
Steam has over 120 million active accounts. Can you imagine how many dead accounts it must have? Yet you don't see Steam closing people's accounts. Ubisoft only has a small fraction of that, I'm sure.
Just migrate accounts you think are dead to their own server if you are having DB problems. If someone wants to use an old account, have a short and easy process for them to reactivate it. Heck, one PC and a backup could store all the dead accounts. Could have it's own separate site page where you could check to see if your account is there.
