Vettel was following the racing line by moving to the outside. Regardless, the issue isn't what rules were in place last year/ this year OR who gave who more room. The issue is inconsistency by the stewards, and Alonso's 'untouchable' status. Alonso ran DiResta off in much the same way - in the same race, on the 1st lap. For that matter, what about DiResta pushing Senna off track too? Same argument, no penalty.
And to specify... The rules are there to protect against rogue drivers being too aggressive. If this incident involved an HRT driver, it's doubtful SV would have received a penalty.

IMO, Di Resta move was more blocking and pushing Senna off the track, it was more obvious than the move between vettel and alonso at Curva Grande.

But it wasn't a surprise that the stewards are inconsistently handing out penalties.

Looks at the reasoning they used to ban Grosjean.
"It eliminated leading championship contenders from the race."
This is a very risky reasoning to hand penalties to drivers.

Sometimes I don't see placing an experienced driver in the stewards panel can help.
Also, if its wrong, at least its consistently wrong. That'll be better.
