Everyone bears some responsibility if you've ever interacted with any entity that profits off of TM or helps TM make profit. I don't find it's particularly useful to spend any thought on what people with minuscule responsibility should do differently. It's just bike-shedding when there are important problems to solve.
Yes, but I think they still have some responsibility, even if they say "I was just following orders!" [1]
