Censorship hurts miners in both the short term and the long term.
If there are transactions that actually harm the network (such as those causing excessively long block validation times), those must be made invalid with a soft fork.

Spam harms the network
Then why don't you fork the network to stop the harm?... People seem to be very confused and running Bitcoin Knots instead of Bitcoin Purifier, which actually enforces the censorship they intend - https://github.com/rot13maxi/bitcoin-purifier
bitcoin purifier would kick me off of bitcoin, harming me even more than the spam does
Not if your fork had 51% of the hashpower, the Bitcoin Pure chain would reorg the Bitcoin Core chain.
Some of the knotsis might be amenable to that but so far they only control 8.7% of the network
Let's see if that number continues to grow and then I'd like to more seriously propose reducing datacarrier limits at the consensus level
