Trek was in the same position as Nike. It would have been economic suicide to pull sponsorship from someone who has never actually tested positive, was the face of one of the most prominent cancer awareness companies out there, and who, until recently, a lot of people (particularly those who don't follow professional cycling, which is probably 99.9% of Trek's market) thought was clean. I don't condone doping, and I have little respect for Lance as an athlete, but you have to realize the companies were in a tough position, and they are companies...they have to make business their priority if they want to succeed.
