At first the Facebook executive looked like someone who was actually "concerned", but then, I noticed that he would keep giving Facebook easy challenges to solve for them to appear "responsible" (usually during times when they were already being questioned), while viciously attacking competing companies.
His positions on things like end-to-end encryption would be strangely specific and tailored to whatever Facebook was willing to do at any particular time.
For instance, Facebook had already done E2EE for Whatsapp but kept delaying it for FB Messenger. He would come up with very specific arguments for why Facebook was in the right, and how FB Messenger was somehow "different". He would later forget these points after Facebook rolled E2EE out in FB Messenger.
At the very least, that is a less intrusive intervention than that other one, and yet, because Facebook does that other one, that is the one he thinks is gospel.
