I think it's absolutely fair enough that people, through communication, limit the power of capital if that capital is used to harm people, or a system. Period.
And anyway, in this case, the 'bad tron actors' haven't actually had their capital, as such, limited, it's still on Steem!
So I'm not even sure if there's a case to answer about the selective air drop?
I'd say let's start by forgetting Steem ever existed - a group of people decided to set up a new chain and decided to be nice enough to airdrop some tokens to their supporters.....
Now the challenge is, well, everything that goes along with setting up a new chain!
That's a core tenet of PoS systems I thought?!
I agree, but there are those who believe in allowing people with capital more freedom to do as they please with it, I'm generally of the view that we need more constraints.
