I thought it's a common knowledge most/all are doing it in one way or the other. Same as professional athletes in many sports, ie cycling - you cannot be really successful without any hacks/borderline cheating, it's more a matter of being few steps ahead of doping tests and current rules, thriving in the gray area.

I simply don't believe anymore there are any clean athletes in first 3 places in any sport where there are significant money involved.

And most people are happy to support this indirectly via their support of things like Olympics which became lately just hunt for sponsors. (I don't watch those anymore, rather will spend the time actually training, with friends, in the nature etc.)

Same for cars.
