Just ask i4i how ethical MS is. MS just paid nearly $300 000 000 in damages for patent infringement on a working product that was the basis for their business. This claim by i4i which MS fought for nearly 5 years all the way to US Supreme Court and lost.

Look at i4i's website. They a are working business not PATENT TROLLS which a lot of you Loverock Davidsons claimed they were.
