His actions initiated a major crash (in which we are lucky no one was seriously hurt) at the most dangerous part of a Grand Prix, the start. I'd say it was pretty bad and a penalty well deserved imo.

There's been worse crashes too without such penalties, but this was probably taking into account all the other first lap crashes Grosjean has been involved in.

BUT - there's one thing definitely wrong with the decision - stewards said this as part of the reason for penalty: "It eliminated leading championship contenders from the race" - why the f#%k does it matter how the people involved in crash are positioned on the championship table?
That's practicly like saying "feel free to crash as long as the ones you crash into aren't running for the championship win"
