No it won't. There are plenty of options for those that may not want any of the Tek Teir stuff.
Primitive Plus - Very unlikely to get any of this
Extinction Servers - Very unlikely to get any of this
Single Player - you can do what you want
Private Servers - can have Tek Teir disabled
There's plenty of options. The only ones that won't necessarily have a choice are those that will only ever play on official servers, and that in itself is a choice.
So no, it won't kill the game.
