The only people that have problems with BB30 are those like yourself that don't understand the design and understand root cause. This thread has a nice subset of those that are making judgments without understanding the physics involved. When BB30 is set up properly 'it can't creak' be it with wave washer or mechanical preload locking collar. Both are effective.
So, at this point, I don't know if you are desperate to defend a design that you feel like you had some part in creating, as you claim...
Or if you are just trolling. There are lots of ways to discuss an issue without always implying that everyone who disagrees with you "don't know hat they are talking about", or "it's too deep for them" or "it's rubbish". The irony is that "the physics involved" is really pretty simple" provide a laterally stiff enough installation that nothing moves under loads.
It really doesn't matter. BB30 units are notoriously noisy, and we have fixes.....while you continue to insist that everyone else "doesn't understand" even though we have actually tried all your recommendations before resorting to the other methods.
BTW: I don't have any Campy Ultratorque setups and I had never heard of "The Rogue Mechanic", so I looked it up. The common theme between BB30 and Campy problems: the wave washer.
The Rogue Mechanic's video is really a very good solution, even though it is a PIA to precisely select washers. BUT IT WORKS.
Otherwise, it appears to me that Campy bearing cups are similar to shimano hollowtech. Why doesn't shamano have so many problems ? : The crank is preloaded against the bearings AND THEN RIGIDLY CLAMPED TO THE SPINDLE. The common theme among relatively problem-free systems: RIGID CONNECTION....no wave washer.
Unbiased readers can choose to do whatever they want with their BBs. It is not worth arguing about with an insulting troll.
