No, because they'd simply decide not to sue you if it would garner bad publicity, and certainly no one is going to care that they could have. The only way patent law will change is when its faults begin to hurt moneyed interests (like anything else in Washington, really). It does seem to have some bite in that regard these days, so there certainly is some hope.
Yes, but but right now even if they get hurt a little by it, they also have a lot invested in it, and they stand to make more money by joining the game an suing others.
Also, patents did start to hurt the financial industry, and they simply gave them special powers to fight the patents, instead of overhauling the patenting system or abolishing them for everyone's benefit (except the patent trolls).
Exactly - nobody gets sued unless they have enough money or competitive position that the suit is seen as profitable. Nobody really has any sympathy with Google or any other large company, so there isn't much "outrage factor" involved. I think there is a pretty large human cost to the software patent system, but a lot of the cost is in discouragement of innovation and misallocation of resources.
