And other drivers who berate their team in public are unprofessional too? Because I can think of one, who criticised his team in Australia, who you didn't voice such concerns about. You remember, don't you? I'll give you a clue....He queried who gave him a "freaking terrible" strategy. Not to mention Prost calling the 1991 Ferrari "a dog" (note to the non-factual : Mansell never drove the car Prost referred to, and he actually called it "a truck") and being sacked for it, or him criticising Renault in 1983 for not developing the engine as well as BMW and being sacked for it. It may have been considered "unprofessional" by his employers, but on both occasions he was absolutely right. As is Kubica.
