I think they only ever had one lawsuit, and I believe that they didn't win it. I'm not sure if they wouldn't first try a cease and desist order, but I'm not sure on what legal grounds they would even attempt to have any lawsuit.
But, I sure would be willing to host any serious review by any serious website if they wanted that type of information out there for people to look at. I've also seen a serious review of the Bose system that highlights the shortcomings that it has.... It's been up for several years, let me see if I can find it....
The first hit I got was a bit different, but covers some not so nice reviews, from some decent publications...

The second link from the above link is the one that has been up for years that anyone considering Bose should seriously look at:
