Well I'm going to assume it's some kind of a translation error or it was blown out of proportion for the sake of example. I doubt they would reduce the size of a linkshell to 10 members but the focus would likely be shifted to something under 100. It may also be talking about moving content designed for linkshells away from the 200+ (hell even 60+) numbers and moving it down towards the smaller numbers simply so then more linkshells can participate or even set up multiple groups to do so.
