I totally agree with the scariness of GW the "one and true model" cult.

I don't know about this - I'm torn. Most times, I kind of think it is appropriate - I want a Leman Russ to look like a Leman Russ, not a T-80, or an M-1, or a Gatorade bottle. Otherwise, it takes me out of the world a bit and I lose that sense of immersion and the visuals in my head.
Imagine you're watching a movie - "Saving Private Ryan." The US forces are in the ruined city, waiting for the German tanks to come into the killzone, so they can chuck the sticky bombs onto them. Here it comes... you can hear the wheels squeaking and the treads tearing up the cobblestones... There, over that pile of rubble!

That's my take. If you follow "less rigid sense of the universe" you're no longer playing 40K/Epic/Fantasy/whatever - you're playing "Generic Adventure Game!" Personally, I play GW games because I am a fan of the universe they have created. There are a lot of other systems out there that are probably as good, if not better, but I
like flying skulls, and genetically enhanced killing machines, and guns that fire caseless ammo, yet still somehow winding up spraying shell casings everywhere!
Aside from that, GW exists to sell models - they are not a game company. If they allowed substitutions of their models at events 1) they would lose money and go out of business real fast; and 2) you'd get asshats who come in with a bunch of tokens from "Monopoly" and "Life" saying "Ok, this is my Space Marine Dev squad, this is my SM Tac squad, blah, blah, blah..." We've all seen "those guys" and all know it would happen in a heartbeat.
Does GW have crappy policies? Yes. Do they care about their fans and the people who helped to fund them to their present level of world domination? Nope. Is complaining going to make them change? Nope again. Because they know you and I are not spending any money with them anymore, so we are completely inconsequential to them.
