It's okay, not everyone gets business stuff right away

So yeah, NRS is owned by WBIE. WBIE bought Midway and MK when Midway went bankrupt back in 2009-ish, but kept the main Midway team which re-branded as NRS. WBIE seems to like their business relationship with HVS as they've contracted them to do several ports through the years. The fact that they keep doing so indicates they are pleased with the work HVS does.
WBIE is the big player here, and more to the point, they're the ones that provide the funding and make the business decisions as both publisher and owner for all things MK and NRS.
HVS won't do work for free, WBIE needs to pay them based on the contract they all worked out, and HVS can only touch WBIE's product when they say so since it's WBIE's, not HVS.
Another example is with balance patching. Many people wanted more balance patches for MK9, and it's been hinted NRS always wanted to do so, but WBIE wanted them working on new projects as that's were revenue comes from. Both NRS and HVS need to do what WBIE says, for better or worse, because they're the bosses.
