I wouldn't say it's hypocrisy because if they didn't put up signs prohibiting people to take pictures; then i can imagine evryone taking pictures of the Kaaba, or themselves thus causing much distracting and noise. Consider, that that place is a place of WORSHIp and not a fun fair..
Besides, there's a difference between picture taking and filming and Allaah knows best.
May Allaah guide our hearts to His Obediance. Ameen.[
