That's harsh. It wasn't the best moment and a bit clumsy first corner accident.
But that does not deserve a race ban, perhaps a repremand and fine or 3-5 grid penalty.
Schumi rear ended into Senna in Catalunya this year, he got a grid place penalty.
Turkish Grand Prix 2008, first corner similar incident where it sent a Force India or something in the air. No such harsh penalty given.
Like Ron Dennis said in the 90's to the FIA, "What is the consistancy?"
