There are also protocols such as Stratum V2 which allow miners in big pools to pick themselves which transactions to include in their candidate block.

Another possibility to prevent this kind of miner censorship is to expand upon coinjoins.

At the moment, if a miner wants to censor your transaction, then they simply don't include it will lose the fee of your transaction only, which is like to be a few hundred to a few thousand sats and therefore of no real consequence to them. Let say instead that your transaction is part of a much larger coinjoin transaction, with 50 inputs and 100 outputs, and a combined fee of 100,000 sats. To censor your transaction they would need to exclude the entire coinjoin transaction, and lose out on a much larger fee. What if that coinjoin transaction included 200 inputs, or 500, or 1000? At some point it becomes worth enough that a miner is going to want to include it to cash in on the very large fee, especially over time as we move more and more towards the scenario of fees (rather than block subsidy) being the primary source of miner income.
