Probably because they're replacing the BIONICLE franchise in multiple ways, but they have great pieces for MOCing.

But it seems that Lego actually gave up on BIONICLE and really wanted to create Hero Factory, hence why they've put so much effort into it early in it's run as a franchise. But hey, that's just my opinion.
