Two things:
1. “Those transactions will still reach miners” - isn’t this the crux of the argument? That filters don’t work and they can be “routed around”, so if 0 users update to core 30 and/or run knots, the transactions will still get through?
2. Are core v29 users “motivated by their desire to censor transactions “?
Because they (and v28, v27, etc) just maintain the current “filters.”
