The uniswap massive adoption by the general public not minding the high fees is because of its decentralized nature. The Cryptocurrency world is mainly develop for it to work decentrally which is what people have been clamoring for in particular to exchange. It's glaring that if it changes it nature to be centralized, then it breaks the true Cryptocurrency protocol and might have so many strange effect.
Personally, I would not mind if, in addition to a decentralized Uniswap, there would also be a centralized one and they would be connected to each other. I don't like paying large commissions, because some of the profit is lost because of this. Centralized exchange Univap would solve this problem.
