People tend to use whatever they have to use to be on a platform since these different parsers aren't portable. Everyone is on GH for the code hosting, getting a markdown editor that works is a bonus. If you go to any other community that uses a different markdown standard or even something that's not markdown, people will be using that - not because it's better than GH flavored markdown, but because that's what's available.
Github supports reStructuredText just fine. You can even display images in Readme without any extension, just a plain image directive.
Not true in the slightest. I used for periods of my life StackOverflow, Jira/Confluence, and bbcode exclusively and hated interacting with each of their markup languages.
