This has been true for every instance of every Fedi thing I've ever tried to use or thought of using. And many instances block single-user instances so forget about running your own unless you only want to interact with the absolute fringest nutjob basement-dwellers -- because the "mainstream" Fedi is already fringe.
I once had the dumb impulse to reply to someone who was mad about fluoride in drinking water with "you probably get more fluoride from your toothpaste" and I deleted my account as I started to receive arguments about brushing your teeth, as it made me realize exactly the kind of people I would be interacting with on this network.
Honestly I think this is grows out of the incentives for operating a homeserver. There's a negative financial incentive so you must have some other kind of motivator, likely a desire for influence or power.
