Your righteous indignation might have been more inspiring were it not being bogged down by your semi-literacy and incompetence.
I am not impressed with ownCloud's heavy-handed approach to dictating what distros can provide in their repositories,
Did you read a different message than the one everyone's sharing around the internet, or do you not know the difference between a command and a request: an actual request, at that, not even one delivered at the barrel of a lawyer.
Considering the biggest part of the userbase for Owncloud is privacy- and security-minded sysadmins (running their own rather than trusting the outside providers), I'd say not wanting them to get pwned because Ubuntu's serving out stale versions is a pretty good thing. They're not the package mantainers, and it's Ubuntu who doesn't seem to give a shit here (there's no good excuse for 'we can't take the unmaintained exploitable package out of the unmaintained repository).
I'm not impressed with the attitudes on display in the ownCloud community and I am very unhappy with the way ownCloud's software wiped out all my work files when I upgraded to the "safe" version. If ownCloud was really interested in the sfety of their users and the users' data, this would have been handled much differently.
And thus, the fledgling learns the value of "backups before updates", after landing flat on his beak.
