Nvidia is adversarial too, and a giant pain to deal with. But then since the 1980s there's been a slow pendulum move to suppliers having more actual and self-perceived power over customers. I'm a big proponent of respectfully letting the supplier know when needed I tell them they don't me if I am satisfied or whether its worth the $ spent on them. Always have options. Without options there's no choice. Internal suppliers (in a corp) periodically need to be told the same thing. Mishandling one's customer power in the relationship is an error i don't like to make.
