Fair point. I'd say "We're neutral, unless you attack us, in which case we stop being neutral about you, in particular". I'd still use them if this were the policy.

I mean if they're getting sued for failing to block proxy/vpn services they're being told to be opinionated and they can't be a neutral service. "You asked us to be opinionated about traffic, so we're doing that. Do you want us to go back to being neutral?"
