> There is also the threat of lawsuit. As I’ve later learnt, 51nb was sued by big L on the pretext that the images and website contained trademarked terms. However, the real reason was revealed that 51nb actually owned the tp.cn domain name and big L wanted it for themselves. Even though 51nb actually won the lawsuit, it hurt their financials badly and they were very reluctant on continuing these projects.
Magical thinking. Of course you can state matter of factly "this is not a Lenovo product" without violating trademarks.
OTOH maybe there is a real risk of getting sued, even if the lawsuit doesn't have merit. CentOS always avoided mentioning Red Hat and refered to the "upstream vendor". I think this was an agreement so that CentOS didn't show up as the first result for "Free Red Hat clone" and it was slightly less obvious to decision makers what it was.
