with the clause that the storefront can ban/delete/deactivate your account for any reason.
I think you’re speculating in order to make excuses for a corporation. Show us the clause that applies in this case, and I will retract my statement.
Edit:
It’s disappointing that several people replied to me with walls of text to lecture about things that were not disputed, and in some cases not even relevant. We know online game stores typically license them rather than selling them, folks, and Valve’s license terms are not Ubisoft’s terms. Kindly read before replying next time.
One person actually brought an Ubisoft inactivity clause to the table. (Thanks, @LittlePrimate) Interestingly, that clause seems to be present only in the terms of service for certain regions. A quick search doesn’t find it in either the Canada or United States versions, for example. I wonder if that’s due to better consumer protection laws in some jurisdictions than others.
So depending on which regional ToS the gamer(s) in question agreed to, Ubisoft accepting money and then revoking access might or might not have been fraudulent behavior.
More importantly, it’s ethically wrong, and no amount of legal maneuvering will change that. Screw Ubisoft.
