That's one way to look at it. Another might be that there are always questions over the legality of the Red Bull, so Vettel doesn't deserve it either.
Or like I said last post - Alonso has had no help from Massa in a race (as regards taking points away from Vettel) while Webber has cost Alonso some 19 points by my calculations.
I just think Vettel is an ungracious arse and I'd take anyone above him winning the championship tbh. Every time he gets beat he has an excuse.
About the legality - I am no RedBull fan, so I've been quite critical of them pushing the limits of the rules. On the other hand, I'd much rather prefer a team to push those limits, than another team shafting one of their drivers to give their No. 1 an advantage.
If you look at it from another angle:
Webber: 2 wins
Vettel: 5 wins
Alonso: 3 wins
Massa: 0 wins
Between them, Redbull has 7 wins, Ferrari 3 wins. If RedBull would give Vettel the same kind of support Ferrari is giving to Alonso, I have no doubt the championship would already be well wrapped up. And I like Webber, I think he's a lot quicker than most people give him credit and I am highly critical of how much the team supports him and while it may not be the equal grounds that Button enjoys at McLaren in regards to Hamilton, it's a far cry from what Massa is receiving at Ferrari.
Maybe that is Massa's own fault, by not performing stronger throughout the season, but does it make it right for them to make their no. 2 driver receive a penality in order to help his team mate? How far away is this from having a number 2 driver crash into the walls to get the safety car out on time to give their other driver a win? Not very far IMO.
No, IMO Alonso does not deserve this, not by a long shot. I might not think Vettel deserves it either, but with 7 wins among RedBull and McLaren imploding on their own, it's hard not to give it to them. I might not like them, but it's hard not be impressed by the way the team just seems to get so many things right, over 3 consecutive seasons.
BTW: Just out of curiousity, when did Webber cost Alonso points?
