I think you could describe the systems that google/fb use internally as paas despite not being externally facing - they have internal teams supporting a platform that then hosts apps and services from 100s-1000s of teams. I know what you mean about control but things like kubernetes were developed for Google's internal paas so they do kind of have control despite the level of abstraction. For us normal people at more human levels of scale - I agree its wise to be skeptical - serve your users in the simplest manner and don't get sucked into HN hype. Its easy to get an infrastructure inferiority complex :)
