This is all pretty normal. I also suspect that these type of trademark issues are far narrower than most people assume.
For example, Facebook is currently pressing a website called "Teachbook" to change its name (or at least its suffix). However, it looks like Facebook is not (and most likely cannot) control the use of "-book" as a universal suffix; e.g. if I make a site called "readbook.com" that is dedicated to literacy, Facebook has no case. Teachbook has an issue because it is, at least in part, a social networking site for teachers; there isn't much reason to doubt the name was derived from Facebook.
As to protest websites, as far as I know you often can get away with appending "-sucks" to a website. However, you may well face a lawsuit if you append "sucks" in a commercial context, e.g. using "dyson-sucks.com" to try and sell 3rd party goods for Dyson Vacuums.
