Exactly, thank you, we are on the same page! It's great to be able to use our own devices and not have their compute coopted by a third party.
I'd rather not have intensive compute needed shifted onto my personal machine which I want to use for something else.
I am not a "third party" on my own computer.
By that logic, any software you run that isn't fully built by yourself is "third party" therefore you shouldn't run anything at all on your machine, thus obviating the need for it entirely.
