Legalization
Let me first state that I thought it was a strategic mistake of Google not to buy Sun Microssystems. Instead they thought they could get away with nabbing some parts and claiming it was open-source. It wasn't. Even Sun had tight restrictions on which parts of Java were open-source and which weren't. And the ones that weren't were the ones that they made money from.
What really bugs me is the "legalization" of the entire tech industry where thousands of lawyers are now needed to navigate though the patent and copyrights swamps and which will eventually stifle innovation and produce even more monopolies.
