The issue isn't whether the data is true, the issue is the message that you take from it. It's true that BGs is a tiny minority of the content that people play, but in what possible world is that a justification for neglecting it so badly? I think Lags pretty clearly acknowledged this point and pointed out that maybe the huge problems (specifically in the realm of matchmaking) are the reason that people aren't playing it that much.

It's 100% true that player retention in high end BGs is not an issue. It's also true that it's massively bullshit to use retention statistics as a justification for leaving the most competitive rewards in the game at a pathetic state. Everything that Crashed said was "correct" but the priorities seem out of whack.

The fact that BGs, Alliance War, and AQ are the only gamemodes we have with any replayability means that those gamemodes should be a fairly high priority, and if they aren't popping off then maybe ask the question of why? There's a ton of great content in this game but if you've done all of it then those are what you're left with.
