I think I get where you're going with this, in that, the burden to run this and review the source is too high, that it almost seems like a waste of time. If that is your point, then I agree with you.
I don't know much about docker, but doing a "curl | sh" peeks my interest, then downloading additional binaries into /usr/local/bin, I'd want to take a closer look. Obviously, this is a case by case review, till it sits well with me. If I was going to run this in production, I'd want to have a really good idea of what this was doing and what to expect, so I'd probably take a closer look at the source if it was not clear from the documentation.
Completely non-judgmentally, it's piques my interest, so you can spell it right next time. (I have the opposite problem: I spell things right and say them wrong.)
