Grand Opening Friends Arena

We got some free tickets for the grand opening of Friends arena here in Solna. The show was all nice and the feeling of been there was all good. 
But there is one thing that I cant let go. On the back of the ticket there are this rules that say what you can and cant do. One thing that I peculiarly dont like it the rule: Camera are not permissible to bring. Befor the show was starting they wanted us to use our mobile cameras and send pictures to Facebook and other social media... 

Change the damn text on the ticket or confiscate everyones mobile phones. You cant have it both ways!

I did bring my big camera just to hope to start an argument, but that did not happen.

I put my pictures here:
