You are making up arbitrary definitions to suit your silly argument. A boat is a form of personalized transport with an ICE engine, a steering wheel and seats, even a windshield etc. so it is clearly a “car” 🤡

And boats are a variety of car if they have an ICE, right? 🤡

You are also arguing in bad faith, because cars are not the same as internal combustion engines. You might be able to argue correctly that tractors replaced farm animals for productive use, but tractors are not cars.

The point is that horses got replaced by trains, trams and bicycles for most people long before cars became widely used.

Wordpress has a well working ActivityPub extensions that is developed with official funding by Automattic. You can interact with Mastodon quite well via these extensions.

But yes, Wordpress is kinda shit otherwise.
