There's no way that this is intentional as regardless of what you think happened in the spygate thing McLaren aren't stupid enough to do something like this, especially not so soon afterwards. The system is already somewhat controversial due to being made by McLaren in the first place, they just wouldn't be able to get away with such an obvious infringement of the rules.
However, this does need to be addressed as while McLaren might be under suspicion having developed the system, all teams have to use it, so there's really nothing stopping the other 10 teams from hitting all the buttons at once and blaming it on McLaren.
