It's not a matter of belief, IMO, it's implicit in 'conservatism' (allow me to generalize a bit here). The average conservative person is relatively averse to taking big risks. A lot of these 'new media'/'new tech' companies are intrinsically huge gambles. Twitter, Facebook, even Amazon, didn't make money (and actually bled money) for a long ass time until they eventually found the model to make money (and in turn, somewhat diminish their initial appeal).
Conservatives are much more likely to wait it out and buy/join an already profitable enterprise, IMO. That doesn't mean there's no conservative innovators, etc, but the mentality is certainly different.
Like I said, just my opinion, there's no scientific basis for this.
