We're on the same page that an FC has to be distinct from a personal house. The point I'm making is that the current handling of SE does not make for a safe environment especially for the members, as the Master already has complete control and can mitigate any damage that a member can inflict to the FC. A member basically plays Russian roulette with free companies.
People were kicked for no good reason. In duty finder this can be reported, but in FC it cannot. The Master was not even subbed when he kicked the FC members, he just logged in during one of the free log in weekends. He then never played again until Heavensward. He did not lose the plot even after six months and came back as if nothing happened. I was harassed in FC environment. In Tell it can be reported, but in FC it cannot. The environment does not change the gravity of his words, the only difference is that SE would not touch the issue.
Square could simply view the FC and chat logs to see if any of this was true, and make a decision based on that.
In other games, I have also joined guilds but this is the first MMO wherein a lot of content is (at least initially) gated behind the guild feature (gardening, chocobo training, chocobo dyeing, company workshop).
