97.7% of tokens launched on Uniswap were scams and rug pulls
It's important to note that Uniswap is decentralized and anyone can "list" anything for trading without asking anyone or going through any process. This means there are thousands of tokens, probably millions in the future, available to trade.
Users do not see these tokens unless they actively search them out. Uniswap uses the TokenList standard (https://tokenlists.org/) and by default users only see tokens such as the top 100 projects on CoinGecko. There are many lists created by reputable players such as Aave and Gemini which cover the entire gamut of projects users want to trade without exposing end users to scam tokens.
I believe this is a good system and has worked well as having any kind of listing process or even a DAO introduces subjectivity and provides points of capture for bad actors. With an open listing process and standards like TokenLists we can say that Uniswap is truly a public good and will be around as long as we need it which provides a guaranteed way to swap any asset for any other asset no matter who created it or how controversial it is which is a good primitive for humanity to be able to rely on.
