The distribution was meant to reward all the users who had used Uniswap before it was announced, this automatically makes the community more loyal to the system to a degree. Rewarding bandwagon users who made a deposit just to get tokens would dilute the value of not only the token, but the integrity of rewarding longer users.
I know I’m not the only one who’s had lots of ETH and other tokens tied up in Uniswap LPs, not because we ever expected governance but because we wanted to contribute to a better monetary system.
This, at the end of the day this should be about the betterment of DeFi as not just a “fairer” financial system, just a better one. One of the fundamental problems with traditional systems is the instability that arises when a very specific group gets added to the community. In this case, long term users and early adopters vs. short term traders and users who didn’t risk their portfolios in a new technology.
