A lot of visionaries are misunderstood because they can "see" things the others can't at the time, and it doesn't make sense to them, which is why they think they are "weird" or "crazy". From that point of view, Richard Stallman was also a visionary, even if it took 2-3 decades before his visions of states or companies putting backdoors in your proprietary software became true.
Manager to programmers: "Hey that weird free software guy thinks we put "backdoors" in our software, whatever that means. Maybe he's right and our competitor do this already!! ...Quick, code a backdoor into our system too, we don't want to fall behind!"
