Its not like they can take down the game and say, "Hey, we'll have everything fixed in 12 months. Come back then!" For better or worse (and lets be honest, its lot more of the latter than the former), the game has already been released. People spent $60 a pop to be able to play.
So instead of shutting everything down, SE has wisely kept things running while giving players two updates a month. And players get to play for free (minus the $60 investment of buying the game).
What's SE supposed to do exactly? Shut down the servers while they fix everything? Release no updates at all until everything is where it should have been at release? They've opted for the lesser of all the evils.
