I haven't found this "group" feature to be very useful, but it does seem to fill a niche for some people. As has been stated elsewhere, the moderator gets to run the group their way, and if people don't like some of the restrictions, they don't need to participate. My answer to those who would like a group with a certain topic, but who can't conform to those requirements, would be to start a group of their own, and moderate it the way they like, and hope that the people who liked the other group but who chafed at the rules would migrate over to the new group.
I know the moderator of a group can set their own rules and if I dont like them I dont have to join and could even create my own group. But there are some interesting groups Ive enjoyed reading and at times would like to add my two cents to (if its even worth that much :D ). Anyway the user miev123 is moderator on a number of groups like Everyday Naked Living and on those groups the rules are:"MUST BE CERTIFIED!" "NO" Absolutely "NO" Private, Or "This user only allows picture/video access to friends," Blank or Empty profiles. Must have at least 2 full frontal nude photos w/ face Must have profile pic. For true nudists who want to meet or share with other true nudists!
I think all the extra hoops are for shit too, and I'm not about to change my profile to get in. I share as much as I'm comfortable with.
That being said, it's his group and he can run it however he wants. I don't feel the need to be a part of something that forces me to compromise my comfort.
