“I should have access to a billion-user ecosystem and hosting and serving and discoverability for free. Never mind that every other platform also costs something to publish on it.”
OP never actually said any of that. You're assuming that that's what they think, when they actually might be content with a much lower percentage. Ask questions of people to get clarification, as user htk did, instead of insinuating they're ignorant asses.
It costs nothing to publish on Windows, MacOS, Linux, Android (it costs to be on the play store but not to publish). Plenty of free .apks on github or itch.io for example). Not sure where you got this idea that "every other platform also costs something to publish on it"
