Umm… one of the major reasons I stayed pledged while doing Power-Play oriented BGS work was so that I could be opposed by players supporting the Federation Powers.
You can be opposed without that pledge.
My CMDR has never officially joined any PP faction (the carrot of marginally better equipment is not remotely enough to overcome his distaste of such formal entanglements), but he's certainly done PP oriented BGS work, and been shot at for it. I'm playing a combatant, but more of an insurgent or saboteur than a line infantryman.
PvP enthusiasts or however you may call them, along with the gankers, lawfuls, PvP bounty hunters and PvP BGS/powerplayers are probably the loudest and most visible group (flooding platforms like Youtube with combat videos), but I have the sneaking suspicion that the quiet, calm truckers and relaxation players outnumber them by an order of magnitude. We will never know though, as we don't get any numbers anytime soon.
I'm positive these groups are so thoroughly mixed that you'd be hard pressed to cleanly separate them.
Be careful with words like "anybody" or "everyone", because whatever you say next will be wrong.
The main theme of many of these arguments is over-generalization, with commenting on things one has negligible experience with being a close runner up.
The big issue for me in Open is the TERRIBLE performance that can occur if someone with (I assume) either a particularly poor connection or low-spec PC enters an instance. Several times when I was last playing in Open regularly, I'd be happily playing - perhaps in a HazRes for example - and would suddenly start experiencing poor game performance, ships rubber-banding, hits not counting and the like, only to notice another player had just entered the instance. This ruins the experience totally, with the only option being to relog.
Performance is usually only bad when the instance is hosted by someone with performance problems. Whatever metrics they use to assign, or more importantly, reassign, the host peer, has always been pretty sketchy.
Back in the gud olden days (2015, probably), when CPU encoding was the only good way to capture high quality video (especially if you had an AMD GPU) if you didn't want to spam hundreds of megabytes per second into your recording array, I made the mistake of starting my recording (with some new, very borderline settings) when I was clearly the host of a very large instance (I could tell by the pixels in the send bandwidth meter) at a CG RES site. Chat was quickly flooded with complaints, everyone was stuttering around and crashing into rocks, NPCs were teleporting kilometers at a time, and I'm pretty sure several players were booted to the main menu. Evidently, the game selected my client as host at some point, probably because I was there for a while, normally had good performance, and had a low ping to the bulk of others present (it was prime time for my location)...but failed to quickly move hosting duties to another peer when I inadvertently overloaded my CPU by trying to encode 1440p60 video with it while playing the game.
I've been more cognizant of my civic responsibilities as a network peer since.
I have never participated in a wing mission. How do I get into those?
Being in a wing of people running them is usually enough, and all it takes for that is to have a pool of acquaintances in your friend's list.
Indeed, I usually reject most of the wing requests I get because people on my friends list like to screw with me by spamming me with wing mission invites cause they know I've sworn off accepting wing missions because I find the reward multiplication an immersion defying absurdity. Not that non-influence rewards really matter at this point.
Seriously, why would someone pay more for the same work, on the same schedule, just because they happened to bring more people? A million ways co-op missions could be incentivized and they picked the absolute worst way conceivable, but I digress.
