I'm saying this to provoke you, and possibly push you toward the light, so please don't take too much offense, but do help yourself to some: Do you have any preference for what the community will call the open fork of your project?
I must add a sidenote because I didn't anticipate it reading as such a scathing rebuke as when it was conceived but, your behavior might be earned, you might be the Linus of motor-bins, but like the way you're acting here in front of your target audience is pretty much like every other BDFL who turned on their community.
You are blessed that anybody shows any interest in submitting any code to your project, and I'm not saying that means you have to go merging every CoC that lands in your PR's, but I am saying that even though someone may be misguided, or may not share your vision, it doesn't mean they lack the potential to be swayed.
obviously you know your stuff on motor-bins, and obviously you're passionate about that. Rather than ignoring and then shunning those who are incongruent in their vision, perhaps you could mentor them on the things you've learned over this time about what makes their idea suck.
last but not least, when someone's giving you unsolicited advice that sounds like complete and utter shite, you respond with "thanks, I'll take that into consideration and keep it in mind". The dev equivalent of that is merge it to a branch, let them polish that turd until they succeed or fail, and then you can be validated in both cases and you've not alienated anybody.
The way you act today, since I've been here about ohhh 2006ish maybe, is in line with every other BDFL who watched their project flourish as a fork instead. You might be cool with that, idk, we only just met, but if that is something you're cool with, you should be up front about that.
