The Facebook comparison is nowhere close though. Firstly, even purely from a services perspective, the per user compute needs per person are quite insane if you take a step back and think about what all has to happen in the background. Then you have to think about how much each user uses facebook and instagram, not to mention other services like video calls and live. Further, Facebook also ostensibly spends a bunch of the resources directly making money by utilising the resources on their ad biz. And then you have all the research and prototype work Facebook does. Finally this also includes office buildings and actual machine expenditure which ostensibly will pay dividends in future years, plus being a factor that OP didnnot even include in this discussion. I'm fairly confident that for the same number of requests of compwrable complexity Facebook spends significantly less than what this person is spending.
