Grow a fucking brain and consider the implications of this little "stunt" where a user who has been playing an old game suddenly cannot play anymore. Why do you think that user will spend their hard earned money to pay you for a new game when they know the company will shut down their servers after a few years?
There are limited ways to fuck this up and the company is looking like doing the absolutely worst in terms of looking bad to their "target audience".
Cool I guess if that saves them a week or a month of a full time Devs time. That's worth more than the clusterfuck of PR nightmare it is going to cause. Nice.
I don't know man. The technical limitations you mentioned should not be difficult for the company that built the darn thing in the first place.
Again, I'd say its a matter of priorities.
