I think you're confusing Roger Ver being the figurehead of all bitcoin forks.
Bitcoin itself was about community and developers for a very long time. There are multiple people who are developing on it including Gavin Andreson, Mike Hearn (not developing for bitcoin any longer), .... Roger Ver. The developer community of bitcoin cash is quite decentralized if you look at it quite closely instead of following the /r/bitcoin troll behaviour.
Contrast that with bitcoin core's developer community - you will see that they are all bought out by Blockstream. And I really, really encourage you to see who is funding Blockstream before you respond back.
Developing something and funding it's adoption are two different things.
Almost the day BCH appeared, all previous forks websites had BCH wallets ready.
It's coordinated bullshit sale but the biggest mover behind was and is Roger Ver.
Blockstream protects their assets, which is also in interest of current Bitcoin holders.
Roger wanted to take over and failed, but still made 30% increase in his net worth by selling worthless junk to tons of Average Joe waiting for miracle to happen (getting the idea of BCH overtaking BTC while reading shill blogposts on Bitcoin.com/Coindesk/CCN ...)
I've sold all my BCH at around 0,2 BCH : 1 BTC. I'm perfectly happy some Average Joe did bought my worthless BCH which I received by doing nothing.
NULS is already very fast with 10 seconds blocks capable of enclosing tons of transactions each. Jason one of the core developers has reached 2K TPS when he modified the block size, we were limited to 800 TPS before he made that change. Again, this was under disclosed as they didn't want to hype the price because they still didn't have their own coins.
