Maybe it's silly to make your own fork, but unless someone else does it and you opt for their alternative, those are your options.
Complaining about how the dev decides to maintain his own project that he does for free is not one of them.
He's been maintaining critical infrastructure for decades. Maybe if you make him a billionaire then he'll have to run his project however you demand, but as long as this is just a passion project of his, it's no one else's business. They can submit bug reports, they can contribute PRs, but cussing him out because you don't like how he manages his own project is just dumb.
