Schumacher and Vettel's incident at the pit lane was a racing incident and Vettel admitted afterward in an interview that he probably misunderstood Schumacher's intent.
Regarding the overtaking maneuver, it wasn't as good as you think. Schumacher's missing gear troubles started around then. A gear was missed and that gave Kimi the advantage going into Eau Rouge.
Sorry to burst your bubble.
Actually, you are wrong. This move had nothing to do with gear trouble for MS. He just locked up into La Source due to his destroyed tyres, didn't get the best exit and Kimi used his chance by using KERS on MS. Otherwise, even with DRS, on the long straight, KR would not have passed MS.
