Perhaps it's people like you that are driving Ubisoft to close/consolidate operations?
I'm not a gamer, but the comment section here is rapidly filling up with comments about Ubisoft selling off valuable chunks of the company and how they seem to trying to squeeze maximal revenue from players, and the players resentment it and are boycotting their products.
If that is the state of their business, it shouldn't be hard to document losses that inspired the shutdown.
I'm not sure how Canadian unionizing works, but it sounds like all the workers did was vote to form a union, there's no discussion of actually approving an agreement with the union, i think the unionization effort is only just starting, there's probably a loophole/lowered requirement to shut down the business in this "in-between state."
