I dislike this for the same reason I dislike Steam -- it's a centralized account which has potentially hundreds or thousands of dollars worth of value.

If the service provider drops support, goes out of business, or decides to ban you, you lose an enormous investment.

I've known for at least three years that I would completely drop out of the console market after the PS3/360/Wii generation. Things are just getting too crappy. Maybe I'll go support Ouya instead.
