Linux is full of companies/capitalism:
- Novell(Attachmate, a company in which Microsoft has representation) : (indirectly)openSUSE
- Red Hat : RHEL/(indirectly)Fedora
- HP (as a partner of Debian)
- Opera/DuckDuckGo/Yahoo as sponsors of Mint
- Sun (historically)
If you're using Google stuff (including Youtube) or Virtualbox/MySQL etc. (Oracle), that's all "capitalism". Personally I think Canonical are just the whipping boys of the moment. That's not to say I agree with everything it does - far from it. But stuff like RMS's call to bullying ("We need to teach Canonical a lesson") doesn't sit well with me. Also when people bandy about terms like "lock-in" and apply it to Canonical for situations that are nothing like true vendor lock-in, I smell a rat. Really if people don't want to use Ubuntu, there are plenty of other distributions. Say what you like and don't worry about what you don't like.
