Miners as intermediaries: extractable value and market

User transactions on Ethereum’s peer-to-peer network are at risk of being attacked. The smart contracts building decentralized finance (DeFi) have introduced a new transaction ordering

It Depends

It depends, really. Some miners on the Ethereum chain, like Ethermine, use non-conventional ordering for their benefit, aka they generally don't do the by-gas sort.
