Didn't say you were wrong at all ...
Well. You are apparently smarter than I thought.

I'd just like smaller maps to match the smaller subscriber base...
And to see all the former players give it a go again to increase the number of red planes every evening...purely selfish reasons 
I have agreed with the prudence of trying smaller maps with the absolute minimal distance between bases for AHIII.
I have even offered to help make some of those if HT wanted to try and stand up a AHII server.
I would love to see 500 players a night back in AH. I have made concrete suggestion along the way that I think are things worth trying.
I won't however fault other player's play styles as long as they are abiding by the player agreement and not hacking. I assign no personal moral or ethical weight to any of their in-game tactical choices. I do not demand that other players play by my personal choices, no do I accept their hubris in telling me how I should fly.
If you think brow-beating players into adopting your personal standards is going to add 400 more players...then good luck with that.
If I agreed to stay silent so I won't be attacked for pointing out the obvious, it still wouldn't work.
No one is going to abide by any "unwritten rules" that weren't already what they wanted to do, and isn't going to accept any private player's attempt to define those if they don't already argree. They will only follow what they want to do and what HTC enforces through player agreement or code.
Sorry if that makes some people pout to hear that outload. But it is what it is.
