We could have legions and legions and legions of people running Knots nodes... Only a small number of 'other' nodes have to 'not' run Knots.

And the spam transactions will still get through to miners. That's censorship resistance, even for the spam (and I 100% agree it is spam).

Fortunately 99% of the spam is sub 1 sat/vbyte so is easily outbid if people want to use Bitcoin which is the greater question in my opinion.
