What is the share of revenue from US? I would guess it's not thaaat far from 50%. The median income in the US is like 20x of India, so presumably ad views from the US ought to be quite a lot more valuable. I would guess EU + US is the vast majority of revenue.
The post they're replying to says "half of their customers", which implies 100% of their customers are in America, which is obviously completely wrong.
The number of users matters much less for FB. The amount of users which can be monetized matters much more and the CPC for US users is always much higher than other countries.
At this point, with the impact they have on the global stage and the fact that they will only pay their taxes where they want, it's a but irrelevant to keep this frame of thoughts.
