No longer choose map on gow4

I saw someone made a post about this before, I still cant wrap my head around somthing like this. Does anybody know if TC purposely disabled map selection or is it a bug?

The only reason I could see TC doing this is to encourage people to play gears 5. But I hate to break it to ya, but I would rather play the worst maps of gow 4 every game, than play gears 5.

Additionally, if this is an intentional move, this does nothing but discourage me from playing gears 5 even more. Why the hell would I support a company that is willingly to sabotage their own product?
