Exactly as I see it also. There seems to be a great chunk of paranoia on the force-everyone-to-open side that "all the solos are cheating me and manipulating the game!"
As far as I am concerned, I only did 2 community goals (just to contribute to, you know, the community). I also knew other players, even opposing ones, would get the same benefits/rewards as me, but so what? It was fun.
Otherwise, and from reading a bunch of these forum threads, most of the Solo/Group players are out there doing their own thing. I see no-one going "hardy-har-har! I am pulling a fast one on Open!" - I see mostly people trading, exploring, doing some pewpew... certainly not gangs of people united in their need to screw with things just for the hell of it, particularly in PowerPlay.
What I do see is this: Open guys explaining why they "had" to drop into solo mode "because it wasn't fair." Some Open guys giving tips on how to game the system for Ranks and Powerplay stuff. Posts about (with video evidence) using shield/ammo/scb hacks. Etc. It seems like more Open players than not are the ones "ducking into Solo" and abusing the Mode switching mechanic. You know, the "metagamers."
So please don't worry that I am planning to nefariously undermine your system, or get a Big Ship to bring to Open to fight you, or grape your sister and grandmother or whatever. In fact, I'm about 1000ly away from anybody and that's the way I prefer it.
