All Open Source isn't communism. The GPL license is a form of digital communism. It forces you to open source any additions made to open source code as a way to make things 'equal'.
I'm glad it and Stallman are mostly in the dust heap of history and better licenses, like the MIT, BSD, and Apache have gotten popular.
The irony is that the only open source projects surviving long term are funded by very large corporations.
If you don't care about creating code, none of this should really matter.
The real irony is that what is probably the most important open source project in history has a GPL license.
Dust heap of history my ass.
