Agreed. The theoretical fat-fingering SRE who stopped all access to FB has probably done more to benefit humanity than any other single engineer in recent memory.
We should be careful to not take our values from a spreadsheet.
If this is the event that teaches someone that Facebook is not the Internet, that’s a benefit to us all.
Seriously though, is the net utility of Facebook even positive there? It’s not like those businesses couldn’t interact with their customers over literally any other medium.
