If Netscape has sued MS and won an injunction a lot of people would have cheered. Which brings up the old 'who's most like MS in mobile today?' question...
Microsoft made a netscape clone and gave away the product for free. Google made an iOS clone and gave away the product free.
Besides, Android device manufacturers effectively "pay" Google for Android in search traffic (or reduced revenue share from search traffic).
Actually google pays the android device manufacturers, not the other way around.
From what I've read on some blogs they never give numbers showing their profit or loss from Android, and looking at the situation from the outside I'd think it's more likely they're losing money on it at the moment.
.... you mean like using a near monopoly in search to finance paying manufacturers to use Android?
