I believe you're wrong. The vast majority of "linux users" don't buy into RMS's particular ideology. RMS proactively describes the differences between the OpenSource and "Free Software" philosophies.
Most Linux users might not buy into a boycott of Ubuntu -- in that sense they reject RMS's ideology.
But I think few would argue that proprietary software does tend towards bullshit -- the very DRM and the like that RMS is calling malicious. They might not go around calling it malicious, but they wouldn't consider RMS's attitude there extreme, just the actions he advocates.
And malicious has strong connotations..e.g malware, spyware, which most "linux users" wouldn't necessarily apply to developers of legit proprietary software.
