The Stallman Cycle:

    Stallman makes claim that Proprietary X is bad due to Y.
    People call RMS a nazi, purist, radical, extremist, fundamentalist and by not using Proprietary X, then end of the world of free-software will come.
    ~3-5 years after RMS made claim, Y happens.
    People moan, complain, and ask "Why didn't we foresee this would happen?!?!?"
    Cycle repeats, with a new issue.
