About ships and techsells, SRP is open for everyone. As for diplomacy, I don't think [KNF]s opinion about =LSF= and [LN] flying in Kusari have been considered for any diplomatic changes. As for the rest, I don't think that official factions are having fun, nor would they like to bother with their "rights". Plus not every player in the faction can do that. It's only a thing for a leader, not every single member.
Also, restrictions in factions are natural thing and are to be expected from any proper faction that doesn't want to turn into a mess. But when a player have alternative to be restricted or not only, there's really little chance that they will choose first option. And that is basically what the choise is for them at the moment.
