This conflating of purchasing with trusting is harmful. It's an ongoing trend I've seen with large tech companies, with arguments of the form "You accept a tiny X, therefore your rejection of the giant Y is invalid."
We buy things from companies we don't implicitly trust all the time, because we can isolate and verify those things.
I don't always trust the supermarket to sell me non-moldy produce, but I can look at the produce and see whether it's moldy.
I don't trust oil companies not to destroy the environment, but if they sell me bad fuel it will be very clear.
I don't trust OS makers, but I can run firewalls and network sniffers to verify that the OS is behaving reasonably, and isolate it when it isn't. Until I can't.
