It just feels like "it's a job" is more of the zeitgeist these days.
And yes, I'm also well aware of what came before 'my time' - mainframes and such were definitely an era where the power was more with the large companies. One of the reasons Linux (and *BSD) was so cool is that finally regular people could get their hands on this powerful OS that previously was the exclusive purview of corporations or, at best, universities.
As to cool projects, sure. They're fun, interesting and creative, but perhaps not part of (a very vague, admittedly) "something bigger", like "the open source movement" was back in the day.
