Unfortunately, you've inserted yourself into a conversation where this is what we're talking about. If you want to talk about something else, maybe start your own thread.

The point of contention here is that Atlassian's wiki is far easier for nontechnical people to deal with than pure markdown and git. And yes, from their perspective, it Just Works. They never wrangle with syntax, there's a massive plugin ecosystem for custom features, and version history works out of the box.
