That is not really the fault of Uniswap because they are built upon the Ethereum blockchain and a swap is a action that requires more than 1 transaction on the blockchain which is also the reason why a swap costs so much ETH for gas fees. When the gas fees are low it does not really matter that much because if you pay 2 or 5 dollars on fees for a swap is not that big of a different if you trade more than 100$ but in times of extremely high gas fees like during the time when the image you posted was made uniswap is almost unusable for normal and smaller trades. Who would make a swap that is worth 50$ if he has to pay 80 dollars in fees for it?
