What's the problem with Game Freak nowadays?

Eh, B2/W2 is its own game I'd say. 8 main games.

That's always made me curious - I feel like I've seen a lot of debate over whether B2/W2 are their own games, or rather more "ambiguity" than debate. 

What did it add and why does that seem to be not always acknowledged? 

Black 2/White 2 is a direct sequel to BW, so it has a different story, plus it adds a tournament mode. Other than that, it's pretty much the same.
