Does using Git contribute anything of value to the documentation that you could not possibly get without git?
The answer is, of course: no. You just want it because it's familiar to you. Which is fine... if you were the only person using it.
Confluence is actually the best solution, hands down. It has a WYSIWYG. It supports Markdown. It has an API. It versions all content. It has fine-grained access control. It does not require granting a user access to a repo to write to a file. It has much more rich content to better convey information clearly to humans. It has full text search. Page management is simple (rename a page and it auto-redirects). And no other solution does all of this as easily or effectively.
The people who complain about Confluence simply don't care about use cases outside their own, and haven't taken the time to learn it. I am 100x more productive with Confluence than you are with Git and Markdown. And real people will actually be able to use what I've made there without learning complex tools or jumping through hoops.
