Today it's something you do to show Microsoft they need you, because today Bill Gates is the world's nicest old man, big companies are safer than the state, and nobody needs any individual person anymore.
It's happened with many other things. For example, early in the last century, journalism was something you did because you didn't want the powers that be to be the only ones heard, and today, well. In the 70s, popular culture was something you engaged with because you didn't want money to be the end-all of your life, and today, well.
It doesn't make open source (or writing or talking about music you like) a bad thing. It's just eventually adults who have money adopt things you like and adulthood and money change people. And when that happens it's not necessarily a loss. Counterculture becomes mainstream after it's _won_. In a lot of ways Linux won, and it _is_ on most people's daily computers today, even though that computer doesn't have a keyboard.
I wish I knew a kid today like I was then, though. A kid that doesn't want mainstream stuff, a kid who thinks we've all got it wrong, a kid who could tell me I don't get it. Because I'm sure I don't "get it" the way adults didn't get it in the 90s: I just don't know what "it" is anymore.
