A user was hacked so they stop allowing him to update their software?! So that it can more easily happen again?
And they will revoke his account (and license?) that allows him to use the software he bought?! This is like a horror story written by Richard Stallman.
EDIT: On second thought, why do you even need an account to update the software? When I'm updating my Ubuntu, it's the software that's signed so that I can trust the repository. The user is not signed so that the repository can trust them, you can stay completely anonymous. Hell, even Microsoft never required me to jump through any sort of hoops to get updates. I once had to verify my key, that's it. Does Android require a Google account to use the market and get updates? Even if, you still can get an anonymous one.
Why would anyone need my name to update their own software? It happens to run on my computer but that doesn't change anything.
