I think you're assuming an awful lot based on the fact that you haven't been surveyed by Facebook.

Facebook has 1B+ people. Do you know how trivial it is for them to run surveys? 100K population surveys, if they want? Many hundreds of them, simultaneously?

I have no insight into how facebook manages its surveys, but I'd be surprised if they didn't have some sort of generalized surveying platform built in to facebook that allows product teams to independently survey more or less anything they want.
