Peter’s reasoning for this: Wienux didn’t have the proper political backing required. You need more than just a couple of technically minded councillors to make such a big project a success – you need to know that you have the support of the majority.
I'm definitely not surprised - Austria is a notoriously conservative and very bureaucratic country, which is deeply reflected by the political landscape. Pioneers and out-of-the-box thinkers don't flourish in this country (although migrating to Linux nowadays is not even pioneering anything anymore).
