Can someone pleeeeeeease explain the fascination with Leica cameras?

I seriously don't get it. I've looked very closely at tons of Leica photos on Instagram (on popular accounts, not just random one-offs) and online, and I can't for the life of me figure out why it's so 'revered' and this 'amazing' camera. It's so expensive and the quality of photo does not even come anywhere close to dozens of other cameras on the market for half the price. Do they just have great marketing or something?

Can someone explain please?
