This is what happens if you "buy" Activision/Blizzard software - they're driving the service model to the max and will exploit it as much and as deeply as possible. They're the worst of the worst and anyone familiar with their games will tell you the same.

In the end, there's nothing you can do but to put your money into games that respect you as a customer, which is very rare in AAA. These companies hate you. No one will listen to you and nothing will change, as it's extremely profitable. No one will regulate it. In 3 weeks, a dev there will notice that some updater code can break game files which flags people's accounts or something like that, it'll be quietly patched and everybody will forget about it.
