The Blocksize War

The exchanges can open the channels directly between themselves without even necessarily being connected to the rest of the lightning channels more broadly. To be able to do that integration, it depends how many participants you want to be able to quickly send between. And i think there's a clear line of support between block stream and bitfinex and tether. I'm just wondering, how close are these ties, and how much do people within block stream accept these perspectives as well?
