what you lose when you publish on someone else's platform

publishing on a platform is the path of least resistance, and that's exactly the problem. resistance is information. when something is this frictionless, it's worth asking who removed the friction, and what they get for it.
the convenience trade
platforms are genuinely good at the start. an audience is already there. the editor works. distribution is built in. you write, you click publish, people show up. for that you hand over a small, invisible fee that doesn't show up until later.
what you don't actually own
the page isn't yours. the url isn't yours. the relationship with the reader runs through a middleman who can change the rules whenever it suits them. your reach is a dial on someone else's dashboard, and they can turn it down without telling you. the day the algorithm shifts or the terms change, you find out how much you were renting and how little you owned.
the attention tax
the harder cost is what the platform does to the writing itself. a feed optimizes for engagement, so it quietly pulls everything toward what performs in a feed. hooks get louder. nuance gets shorter. you start writing for the distribution instead of the reader, and you don't notice it happening, because the numbers reward the drift. you noticed the feed doing it to you. it does it to writers too.
what owning the page gives back
own the page and the incentives change. the writing answers to the reader, not the dial. the url is permanent, so the work compounds instead of scrolling away. you control the speed, the look, the data, and the door to the reader. it's slower at the start - no borrowed audience - and that slowness is the point. what you build on your own ground stays standing.
the honest middle
this isn't a purity test. platforms are fine as megaphones; post there, point home. the mistake is letting the rented megaphone become the only place your work exists. own the page. syndicate from it. keep the home base yours.
