It’s quite common for people to easily fall to the idea that Free Software might resemble some qualities of Communism. But when someone try to go deep in understanding of both Free Software and Communism, they can see some contradictions between the two even in both Theory as well as in Practice.
Communism is seen as alternative to Capitalism by some and it is seen as the evolution of capitalism by some. When RMS was interviewed on this aspect (not in the aspects of communism, but in the aspect of Capitalism), whether could Free Software thrive in the Capitalist Society, he made a point there. You can watch the entire interview here.
In another interview by newyorker to RMS,
When I asked him whether his message is received more readily in countries with a stronger political left, he said, “Yes, it is. Basically, Americans have shown that they are politically naïve. If you look at how successful plutocratic candidates are in the U.S.—you can get Americans to vote to give their money to the rich. You have to just say certain predictable, silly things to them, and most of them will be fooled.” He paused for a moment, then added, “The point is, even though it’s sad to see people being foolish, there’s no use giving up. Nothing good can come of giving up. That just means you lose completely, right away.”
Nevertheless, if someone can jump to a conclusion (whether it is related or not related) by just reading the discussions of this thread that’s something bad. Bad because one need to spend extensive time and effort in reading and understanding both ideology before jumping to conclusions.
