In certain parts of the world, you quite literally do not have a choice. For example: I'm in a rural community on an island. No one uses any other website to post anything, from local classified ads to events to important city/community stuff. The choice isn't to use a better alternative but whether a person here has social contact with anyone locally at all.
No, moving is not a realistic option, especially not moving as far as we'd have to move; even the biggest city in the province doesn't use anything else.
itch.io is fantastic. Mostly indie stuff with some bigger name stuff, but it's by far the best out there for devs.
