According to Button FIA is wants more aggressive racing, presumably, to enhance the show...
"They were never going to penalise him (Niko) anyway, because as we all discussed about four races ago, we needed to be more lenient on drivers because we wanted more aggressive racing. If it had happened four races ago, I'm sure Nico would have got penalised because that sort of incident always got penalised. But these days, in the last few races, it has been viewed that more aggressive racing is better for the sport, so you let things go a little bit more.”
