Very emotional reactions here, whether fuming at the unreliability of the service, or zealously defending and identifying with it, indicate people have far too much invested in this single point of service.
People are saying - "That's me done for the day, have a good weekend!" What is the economic cost of this? On a global scale? The pattern is the same as we've seen recently with Office365 and other cloud services.

It's not like this crowd is typically "helpless", or unaware of what is being done, yet people remain beholden; Github has diversified into a social network and AI tool, far beyond its initial remit as a code repository.
