the discussion isn't stupid, you are.  There's no data that is being suppressed by any authority -- no censorship is happening. Run your node or not, just don't equate mempool policy with censorship anymore.

mempool filters can absolutely have an effect on spam.  Consider a situation of multiple chaintips (happens like every week), on a network of nodes filtering spam, blocks w/ spam would propagate marginally slower than blocks without spam because the spam transactions wouldn't be sitting in every nodes mempool already-validated beforehand.  Miners should be wary of the mempool policies that nodes choose less they wish to produce blocks that could be orphaned, every second counts. (important to remember that nodes can validate both chaintips all the same, filters don't cause forks)

It doesn't even require a majority or even that many nodes to have an effect, every node that chooses to discourage spam txs incrementally increases the possibility that a spam-block (block containing txs not relayed by the p2p network) to be orphaned.  Said another way, mempool filters eventually lead spam-aligned miners to push their luck and pursue forks.
