Then leave. No one is asking you to stay and use the new layout. The people who petition are mainly people who joined facebook lets say an year ago. If you’ve been on facebook for long than a year like i have you would have realized the large amount of changes facebook has been through.
Message to you guys who keeps inviting me for these groups : Stop bitching and get used to the new layout. Soon its going to be permenant.
Just because a few 1000 people join these groups the developers are not going to change it.
