So the only thing this clause actually does is to make it harder to sue them as it's going to be harder and more expensive to sue them as an individual than in a group.
No.
You cannot sue them. You cannot take part in suing them. You cannot watch them getting sued. You cannot help them get sued. You cannot help others sue them. You cannot talk about, think about, or make plans towards any of the above.
THE PLAIN END OF IT IS YOU CANNOT SUE THEM.
