They irritate me. They usually aren't weather sealed whatsoever, and they cost a FORTUNE. For what? Leaf shutter? Other cameras have that. Good build quality? Other camera have that too. Good (expensive) glass? Other, again, have that.
They were once the "known good" rugged option for photojournalists- small, light, durable, high quality- so they were a default. But that era is LONG gone, and I just don't see much of the allure.
Actually, I think I have an excellent idea of what's going on: they've become cultural shorthand. They send a very clear elitist message that you can afford a wildly expensive camera that takes pictures exactly as good as the other cameras out there that cost less.
And that's fine, I suppose. Everyone is entitled to spend their money their way. But recognize what it is. This isn't about a camera- this is about snobbery and exclusivity.
