It's not worth it to sue them because they have such a small market share. And besides, all you say is "likely," not that there are patent violations.Heck, look at linux, there are likely many patent violations in that project, but it keeps happening anyway. It may not seem logical to you, but there you go. Also, this has nothing to do with microsoft's position in the late 90s.
Or you could, you know, respond to their claims rather than just writing them off. That's usually how debates work.Ultimately though, since you seem to know nothing about what actually happened, I suggest you educate yourself beyond lew rockwell and mises and look at the real world before you bring up issues you don't understand.
