There are a lot of people who simply don't care about PvP. There are far better games for that. I play War Thunder. ED has nice flight but it's not really that great for combat. It's too easy for the first person to shoot to win the battle if the ships are anywhere close equal. That puts the combat firmly in the aggressors favor. Luckily I haven't met any yet.
In the end I can't tell the difference between the two modes other than solo is probably smoother and runs better on low spec, low bandwidth systems. If you ignore the people that want to fight there really isn't much difference. Maybe when the MP and comms have improved things will change.
Talking about fairness. What happens when expansions are released? would you fragment the players even more and completely seperate those that don't have planetary landings from everyone else? There's bound to be some perceived imbalance somewhere.
In the end this game wasn't intended to be a PvP centric game but more of a coop one <shrug>
its a multiplayer game , geuss and it would be most logic that players who wont buy the dlc cant play anymore , atleast most if not all mmo(yes its advirtised on the website , read.) i played you cant play it if you dont have the patch/expansion. This way FD can collect some big money too
