But it's easy to imagine a world where that didn't happen and BSD was just killed dead. So no OS X, no iOS, no Android, no ChromeOS, and the only vendor able to stand on its own is the one we all agree had the worst product.
Ironically the world where the Bell monopoly was left in place seems to me to be one where we're all stuck running Microsoft Windows on everything, no?
I mean, fine, there's nuance to everything but the idea that "well, open research isn't so important" seems frankly batshit to me. Monopolies fall on their own all the time (Microsoft's did too!). You can't get stuff into the public space that wasn't ever there to begin with.
