I'd wear the green tights just for the hell of it.
The degrees of separation aspect is interesting. On one side, I didn't take the money so all is well. On the other side I am basically enabling that behavior and saying it is ok for you to do it. With that being said, it is enough separation for me.
It's like me using allofmp3 to get music. It helps me get cheap music and separates me from the theft. It is safe to say they aren't legally selling music that cheap, but I paid for my copy and will turn a blind eye to what they may be doing.
In the end I won't argue that is is ethical. It is unethical, but I am comfortable with the degree of it.
There are always degrees/levels of law breaking or unethical activity. We all have our lines drawn of how far we allow them to go.
