You forgot "the government", which is really #3. Developers usually sit somewhere between "astronauts" and "things that from distance look like flies".

Which is why Microsoft Windows, the most targeted platform in the world for decades, never bothered to give a damn about developers.

I didn’t say that. But if you think MS will ever put developers’ needs before its own, the customers’ or the government’s, you are sorely deluded. They give a damn about developers only inasmuch as it helps their bottom line, like everyone else out there.
