Excellent question and great to see you thinking in the same direction.

Consolidation of various open source projects is underway with projects such as owncloud but it is still very fragile and hard to maintain.

I think a pledge never to be bought out and a way to restrict stock to EU UBOs would be one step in the right direction, then you'll need a massive amount of capital to pull this off. But maybe the climate is finally right to raise a proper amount of money for such an undertaking.

Hmm, I wouldn't say it would take a "massive" amount of capital. EU is rich enough and they don't pay developers as well, correct? Most of the building blocks already exist.
