Why is the SEC suing Uniswap?

As a seasoned observer in the crypto and financial landscape, I must inquire: Why has the SEC decided to pursue legal action against Uniswap? This decentralized exchange, which has gained immense popularity in recent years, seems to operate within the confines of its decentralized nature. Could it be that the SEC sees Uniswap as a threat to traditional financial institutions? Or perhaps they believe that Uniswap's operations violate some of the core principles of securities regulation? Whatever the case, it's crucial to understand the motivations behind this legal action and its potential implications for the broader crypto ecosystem.
