Maybe, but remember that we are the same people that installed/pushed Ubuntu on the computers from our family and friends and gave free support on forums and irc.

We did that because we believed it was a better alternative. So some of us get passionate when advertisements creep in the default installation...

You can't demand anything from a non-free product either so I don't get what the difference is.

However, I can not use it which is how I've decided to deal with this issue.

Can I demand, say, that a website doesn't install some virus/spamware/malware, even if it's free?
