Did you misunderstand? That's niftynei's text and she's not criticizing PoW, the point is that MEV is harder to achieve in a standard bitcoin-style PoW based "election" of next block producer, compared with something centralized or simple round robin etc.

(Iirc this is a problem they try to address in some proof of stake algos - if anyone can see in advance which party will be the next block producer, it leads to undesirable outcomes.)

Proof of Work removes some opportunities for gaining an edge in arbitraging a system, because it makes the next block source random. This randomness makes it hard to figure out who to stalk to get the next block. It could be coming from anywhere.

Disingenuous. The next block is random but e.g. owning exactly 1% of hashing power will over a year turn out to exactly 1% of blocks. I bet that's misleading
