Mechanic says that fee rate variance... will gradually mean greater profitability for PPLMS/Ocean Miners. So there will be less incentive to stick with FPPS even for large miners.

On the other hand, there is a 'compliance cost' or risk to not mining with a transaction-compliant pool. Yes it's 'less profitable' to use FPPS but the lawyers from large miners can/will/have argued that it reduces regulatory risk for large-infrastructure miners.

If there are 'enough' mining pools and enough monetary demand for transactions, then eventually fee pressure will build for transactions, even if those transactions would otherwise be censored by some pools. However overall there are few monetary transactions or fee rates are still low 1/2 sats/vb so this hasn't happened yet.

On the one hand, 'fees are too high' on Bitcoin (altcoiners really like to say this). But in reality they are too low as they concern monetary transactions.

Tldr we need more monetary transactions and education about Lightning in my opinion
