recently uniswap reported about the fee on 27/8/2021 with a fantastic fee price, because many altcoins use uniswap swaps, What do you think?

Thats because of the eth network usage. Its not only about uniswap fees. Anything that uses eth network experience this fee. Yes its kinda frustrating but thats how eth when everyone uses it. I think they cant handle those massive transactions simultaneously thats why the fees increases so much.
But this will change soon when eth complete their migration.
