Excellent point, open and free but only in the way he sees freedom... We are talking about the man who is insisting to call Linux, GNU/Linux and likes to flame people for speaking up their minds, with different world visions...
So he tries to persuade people to agree with him, perhaps passionately, perhaps vehemently, maybe even not so nicely ... but (to my knowledge) he has never used force or fraud to coerce people into behaving the way he thinks they should. That sounds perfectly freedom-loving to me. I'm really not seeing the problem here.
If your opinion of the guy is correct, then his methods will cause fewer people to listen to him and he will thereby undermine his own efforts. This means such a situation would be self-correcting. I've never heard of RMS using force or threat of force to make you call it "GNU/Linux". The degree of power he has over you is determined entirely by how much you decide to listen to him*. The ability to recognize this is generally called perspective.
It's as though some people have an entitlement mentality, a manner in which they are self-centered. It leads to them feeling like they've been wronged or mistreated somehow when they discover that someone doesn't agree with them, won't support or otherwise validate them (probably the part that really bothers you), and speaks against them.
* I started to add "and use his software", but then I realized that's not true - you could use Emacs with the LLVM debugger ... or not, whether anyone else likes it or not, because the GPL and LLDB's NCSA license are compatible. RMS deliberately chose a license allowing this to happen. Did you fail to recognize the significance of that? That freedom means people might do things with which he disagrees does not remove his right to disagree. Are you suggesting it should? If not, what exactly are you trying to say, if you are not in fact expressing another entitlement mentality?
