not all PP players that play in solo/PG are exploiters, but all PP exploiters fly in solo/PG, in my opinion going open only is the best way to combat the actual exploiters. It is also the best way to make PvP a valid gameplay option. PP isn't strictly PvP as there are PvE aspects but PvP does make PP more interesting. That is what this is all about, making PP great again.
Just wanted to add that not everyone that flies in open is out to kill everyone, most are just looking for positive player interaction there is nothing wrong with others being content, as that content isn't always combat.
