I bought some software today, and their license agreement contains a rather odious term. They get the right to use your name and similar details including trademarks in marketing without getting permission at the time, or any notification. Fortunately if they do that I have enough counter material that would make them regret it. Oh, they also get to pull the software any time they feel like with no notice period, including remotely disabling it.
I guess most companies are lucky that no one actually reads these agreements since they pretty much consist of a list in legalese of how the company can be hostile to its users.
