I don't have a problem with any of that. These sorts of IP disputes go on every day. Most big companies have some number of them going on all the time. Usually the parties involved behave in a professional, responsible manner. When they can't resolve it and they have to go to court, they go to court.
Tactics such as trying the case in the press, screwing with other people's innocent customers, and blustering about ultimately owning all operating systems everywhere are neither professional nor responsible. They hurt a lot of innocent bystanders, they hurt the entire industry, and ultimately it's all to no effect. None of the public hoo-hah will move the business dispute one way or the other in the courtroom.
About the only thing I can think of that would be more childish than that is sending employees and business partners into Internet forums to spread the same hoo-hah there.
