It could also be argued that it improves the experience of the many by reducing the likelihood of being instanced with the few.
I don't think the reality of it's function supports that argument very well. It doesn't prevent you from being instanced with the few, it prevents you from being instanced with the few, plus whoever they are instanced with, and in the long run, that is vastly more people.
That's not a solution.
You'd have to stop using it on people I may be willing to encounter, or we'd have to block each other...which would be exceedingly hypocritical and counterproductive from my perspective. I may not like you as a person/player, but our CMDRs may get along just fine.
But you're dictating what the 'experience of the many' should be. And that's wrong.
I could easily accuse you of the same thing.
My desire is to be free from the side-effects of the dictates of the few and have the Open experience the game suggests it can provide.
How about instead of decrying the people doing the blocking, you decry the people exploiting broken game mechanics to behave like disruptive idiots and making people use the block list feature? Because I'll be honest, I'd block those cretins on sight.
I don't agree with your implication that abuse of flawed station C&P mechanisms is worse/more disruptive than imposing one's personal block lists on others in the same instance.
The worst case scenario from the former is the loss of a ship and cargo. The best case scenario of the latter is a non-open Open where anyone can exclude anyone else they feel like from any instance I happen to be in.
Mr. S and Mr. D have been enemies of my CMDR for years, I've wasted dozen of hours trying to foil their obnoxious and exploitative antics, and I find them to be annoying as players/people as well. However, those who are too caviler with block lists are infinitely worse, in my opinion.
