I find it amazing how people keep assuming 2007 was a season with two #1 drivers...
Lewis Hamilton was a rookie with ZERO experience in F1. Alonso was current two times WDC. The only sugestion that they would receive equal treatment is an unquestionable evidence of favouritism towards Lewis. No other F1 team in 68 seasons have ever considered providing equal treatment to current champion and a rookie, because it´s absurd (as time demostrated).
McLaren claiming they would provide equal treatment to current champion and a rookie was self-explanatory about their real interest, later proved with Lewis causing a penalty to his own team after demanding Alonso (and mclaren doing nothing to stop him), or Dennis claim "we don´t fight Kimi, we fight Alonso".... and Kimi won the title
And before people accuse me of Alonso fanboy, I must say I was shocked with Lewis GP2 season in 2006, and I was really hoping for a great and fair battle between both in 2007, a battle McLaren/Dennis ruined... Hamilton was his protege since he was 12 after all and both he, McLaren and even FIA were very interested on Lewis winning the title in his very first season.
F1 agenda, similar to Max receiving no penalti for blocking Ricciardo, when they see a marketing bomb the rulebook becomes secondary
I´m saying all this to explain my point of view, wich is even if they claim equal treatment, they always have a #1, only that for marketing reasons, and also to keep respect to his #2, they do that sort of PR claims. And I agree with that philosophy, this is F1, a team competition, and the team is always more important than any driver so maximizing their chances is their job
