I mean, that’s what they say but it doesn’t pass the sniff test. Which other major service struggles so much with basic scaling? They’re not serving streaming video, they’re not a real-time system.

I would argue they are. You can't cache a git repository and send people what it looked like a minute ago, because someone might have pushed 2 seconds ago.
