Because I would like to return to what the game offered, and as Robert would say, promised in the Kickstarter: pvp piracy.
Not all Pvp interactions, when the game was simpler and better, was about destroying the other ship and because only the rare trade routes where the only real source of, as far as it could be, steady income for players pirates, it was easily avoided by those unwilling to participate. Risk could be assessed and managed.
In the same way that a much improved C&P system (and repaired mechanics) would allow only for hit and run attacks in certain high profit system that, again could be avoided and, therefore, like in the days of rare goods trading, any player who studied the simulation as was intended (best trade routes, juiciest mining spots, likely black holes, best smuggling routes) would be, de facto, giving consent in Open, to player interaction if they entered those locations.
Seriously, the forums where full of information threads about whether pirates where here, there and anywhere and the whole thing was livelier for it.
The destruction of skill based pvp, thanks to engineers and bored billionaires, thanks to overlong and low risk smuggling missions and now skimmer kills produced the mess that Open appears to be (though it's still safer than you think).
You can't blame a guy for wanting Open to return to when he and others (and not just pvpers) found it simpler, more fun and, yes, more Open to all playing styles.
