I am familiar with performance testing of complex product, I agree that it's hard to overestimate the insane complexity of this process. But if anyone has both means and obligation to do it, it's a megacorporation that weaseled it's way into being a monopoly with an iron grip on the world's infrastructure. If it wasn't for that, I would agree that it should be a collaborative effort, but when you're monopoly you don't get to blame third party on your unilateral decisions. "I just changed everything about the infrastructure that I forced you to operate under, now your shit doesn't work and it's your fault actually".
