I really don't think that's an accurate characterisation. Space launch isn't a zero-sum game, and SpaceX and ULA aren't sports teams. You don't have to cheer for one at the expense of the other. After all we're all just humans stuck on a rather small planet, painting ULA in any sense as the "bad guys" is extremely silly given a little perspective. If SpaceX pushed ULA entirely out of the commercial launch market it would produce yet another monopoly, and while Elon's motivations are primarily for the betterment of humanity healthy competition is much preferable.
I, for one, am quite excited about ULA's planned Vulcan rocket [0] which incorporates reusability of the engine section, and hope it will be a success. I'm sure you will find that the most active members of /r/spacex feel much the same way.
The reality is that a lot of people treat them exactly that way. They are on team SpaceX, and they root for them and against ULA, who is seen as the establishment who gets ahead using politics and lobbying rather than tech.
