You might care to check your figures.
Well, a certain online ATC agency has over 50,000 registered members (pilots & controllers) - pprune only has over 10,000 more - we still are a significant number !
PPRuNe has rather more than your suggested 10,000 registered members. At least 4 times as many as that, perhaps 5 times, perhaps even.................................
I am sure you will understand the point.
