EDIT: The fact that Alonso was getting wins throughout the 2007 season means that McLaren wasn't actually handicapping him (not like they did Hekki... though to be fair... Hekki was never in contention). The same way Mark's results show that he's not being given the short end of the stick in terms of team support... well.. until Turkey.
I think they are very different situations. This is a clear part/advantage given/taken away from one driver to another.
I think McLaren 2007 was very much overblown with Alonso just not very happy that Hamilton was matching and beating him. I think he very unsettled by that and called foul, when really I think he was just better.
Quite. McLaren openly said that they wanted to treat the drivers as equals... whereas Alonso, as a two-time world champion, knew full well, just like Michael Schumacher before him, that having the full support of the team behind the number one driver produced championships.
He didn't get it. And to make matters worse, he couldn't borrow set-up information from Hamilton because their driving styles differed so greatly... Alonso with his aggressive turn-in and Hamilton with his more organic style... working from Hamilton's notes would get him nothing.
While it may have been embarrasing for Alonso to end even on points with a rookie... I wouldn't quite say that Hamilton beat him... while Hamilton was clearly the quicker of the two in terms of raw pace... Alonso was better at converting positions to points, and could match Lewis in terms of speed... but Hamilton definitely forced Alonso to reach deep to compete with him.
Some drivers would get a thrill from that kind of challenge. Alonso didn't. Their partnership could have been legendary, but Fernando just doesn't work that way.
It's similar to the Webber-Vettel situation only in that while Vettel is also clearly the faster driver in terms of raw pace (usually), Mark Webber has more experience, more consistency and better racecraft (usually). The difference is: Webber isn't Alonso. He's a better team player. It
could work out if they did the McLaren-style "equal status" thing... but that favoritism, both actual and perceived... has just ruined their chemistry.
