>Large systems are not like hackathon projects where you might understand and hold the entire scope and flow in your mind.

I've seen this argument repeatedly now in a defense of Facebook, recently in a twitter thread where a facebook employee in a discussion about hate speech moderation responded along similar lines of "we are simply too large and don't know what's going on in every corner of the system"

I find it funny that this is used as a sort of excuse or defense. We can draw another conclusion. Like Goethe's Sorcerer's Apprentice Facebook has lost control over its own machinations and is simply too large.
