Maybe, but it's a dim way of looking at other people.
It’s clear the GPL hurts open source. It’s why I’ve never liked it.
The irony being that formerly FOSS companies are turning to dual licensing, "open core", and similar non-free strategies because it turned out that Gates & Ballmer, y'know, like, actually had a point: you need income in order to keep your business running.
And, by the way, you're wrong anyway: GPLv1 came out in '89 and GPLv2 came out in '91. Microsoft was a relatively minor player at that time; its meteoric rise to dominance didn't begin until a few years later.
And I think GPL actually embodies a really positive mindset. To release GPL code is to believe that there are others out there who will help you without intending to get advantage over you or shut you out.
