I never said that Nico was cheating, I did however draw the analogy that in grade scholl when you copied the other guys answer that what it's called. My comment were to address recent fashionable statements that Nico is the hard worker of the two.
So you'd have to agree that if Lewis can't gleem anything from Nico's performance, what does he gain? Yest Mercedes has a policy of sharign data but he's not benefiting in the slightest and so the cheetah loses out the the hyenas. Your assertion is a bit childlike, well Lewis should just go faster... and that's easy to do in a formula one car right? I could understand your position if there was anything to gain, but it's Lewis that has to keep finding the time, and doing the work to find that time and it's Nico's side of the garage that will sit and say, here here's what he did to go faster just do that.
I never said he was cheating, but you can see how that's what it would feel like when the cheetah looses the kill to a pack of hyenas. 
Since you introduced the educational analogy, allow me to interject. Today, we allow students to work together, in groups.
This is advantageous in a number of ways:
- students learn to work together collaboratively and co-operatively;
- in working together, a "stronger" student can share how they arrive at solutions;
- in explaining their strategy, the "stronger" student benefits from learning how to express/explain their solution;
- the "not so strong" student benefits from seeing how a peer arrives at a solution;
- the "not so strong" student also benefits from learning how to express/explain their strategy;
- both types of student get timely feedback from their peers;
- both have the opportunity to develop their own methodology.
Through working collaboratively and co-operatively, youngsters learn how to get along with others.
This is extremely important when participating in the work force, since it's rare to find employment
where there is no interraction with colleagues.
What does this have to do with Hamilton vs Rosberg? Well, they are "products" of a different educational system than some of us here, who learnt by rote. Also, they are teammates in a sport that seems to be evolving technologically, right under our noses, which means it's to their advantage to collaborate and co-operate. Both will come to "problems" in a different way; but, in seeing it from a different angle, a different solution may come to mind.
I don't believe that one is a "harder" worker than the other; I do believe they come at problems differently.
Nothing wrong with them sharing their strategies! In fact, I'd go so far as to suggest it might make them stronger!
