An Ethical Dillemma

I was debating with Erin the other day on the ethics of amateur sports. We didn't resolve anything but it expanded into lots of issues.

Basically the question is this... If a Canadian Olympic athlete (we'll say medal contender so they are invaluable to the team) refused to wear a "swoosh" (Nike logo) on their uniform (I have yet to see an athlete in a sport without one), what would team Canada do? Would they be allowed to compete, should the be allowed to refuse a logo on ethical bounds. The nature of branding aside, Nike is notorious for human rights violations in it's sweatshops (and in the same breath promote equality and harmony through sport). So if an athlete in good conscience wouldn't wear that (or any other logo depending on which companies they choose not to support on moral grounds) what happens?

But it lead to my thinking. I'm working away on the masters degree, and NIST is interested in it. Now whether or not I like NIST, my research can be used by them cuz the thesis belongs to the U of C. Now NIST is funded by the US military, and they are developing robots that use real time 3D scanning for navigation. These would concievably be used in combat. I can't do anything about it, but it bugs me something I've researched could be used on a battlefield. Anyone with thoughts on that topic?

Just some ponderings.
