I recognize that, but also they've stated to be open to suggestions and the sky is the limit.
Player groups are not player managed guilds.
Yes they are making plans for development. If Elite Dangerous continues to be shallow in the massively multiplayer aspects a lot of players will be migrating to this other game called Star Citizen in the near future.
Elite Dangerous sold lots of copies with Steam sales, but the true test is how many players does it retain in the long-term?
Eve Online still has 40.000 active players per day. I think the amount of active players per day in Elite Dangerous has declined a lot in a short time. This could be due to several reasons, and one of them is the shallowness of the MMO parts.
I don't believe the 'sky is the limit'. FD have mentioned that they won;t be turning Elite in to a executive decision type of game.
Player Groups are not player controlled guilds. Nor do FD intend they should be. But, they are what is being delivered. Decision made it would appear.
Your last paragraph has nothing to support it. It is just some vague idea you present to add some scare factor. This game has been very successful, there is no data suggesting anything different.
