It seems to me that because RBR are so dominant (4 race wins out of 5), the media, the teams, the public, etc are all looking for ways to get any devices used by RBR, banned.
Last year we had the flexi wings, which were later deemed legal, after they passed more stringent tests.
This year, we are now kicking off with the off-throttle engine maps (and I'm sure there will be something else, later on in the year).
Face it people, rather than trying to get RBR car parts banned, it would be a lot more productive and fruitful to copy RBR and retro fit their cars with RBR technology.
Personally, I don't think Charlie Whiting, the FIA, the World Council (or whoever) are going to do anything about RBR's innovations. They are just saying things to keep the other teams quiet. Rather than saying, "sorry guys, RBR cars are legal, go away", they are saying, "ok ok, we acknowledge your concerns and we shall investigate/discuss your concerns later on in the year".
F1 should be about technology and innovation and I personally don't care for people who want to prevent this and get innovate ideas/technology/parts banned.
