The Pole-sitter Sebastian Vettel’s team has been forced to ditch rear floor hole package, in addition to its wheel hub design, ahead of the Canadian Grand Prix following commands laid down by the Formula 1 governing body (FIA).
"I think it is all part of this game and of the sport," Horner told Autosport.
"Everybody is entitled to an opinion but we don't lose any sleep over it whatsoever. Technical clarifications go on up and down the pitlane; they just perhaps don't get talked about as much as what ours do."
"The nature of F1 is to push the boundaries and be innovative, and that is what we will continue to strive to do," he said. "Charlie [Whiting, FIA head of technical department] does a good job in taking balanced views and we have got absolutely no complaints with the way the FIA has dealt with any issues, certainly surrounding our car this year.
"I think it is the nature of F1 that teams will look to extract as much out of the regulations that are written in a way that require interpretation, but that is the same up and down the pitlane. Probably Caterham has had to address things on their car at some point but, for whatever reason, they don't seem to grab as much interest as Red Bull.
"Detail is crucial this year. You have to extract performance out of every little bit you have got, and this season with the margins being so tight it will all come down to detail ultimately."
