They're not suing competitors. They're suing people who are profiting from Apple research without compensating them. You think it's good that one company spends billions on research and everyone else just steals it and undercuts them? Don't you realize that that eventually leads to no research being done anymore?
Your statement may be technically true, but in this case it just comes to show the stupidity of the patent system - is making a link from text something Apple invented? Probably not. Did it need to spend billions creating it? Definitely not.
I think reality trumps made up laws, so I don't like your statement, as it just shows conformity to a broken system without any thought at all.
