You make it sound so reasonable. There is a patent gold rush right now. The USPTO is approving thousands of patents that cover the same obvious ideas. Parties that have lost in the marketplace or haven't even participated are effectively taxing the winners by extorting patent fees. Google could pay the fees to the losers and acquire enough patents the reach an equilibrium via mutually assured destruction with their competition, but the market is effectively closed to anyone without the extremely deep pockets.
First I hate patent trolls, but the ill effects are financially not that devastating. Trolls do not kill the geese. No geese, no egg.
And then there are the tech giants, they do not notice you until you get real big yourself.
So yeah, the situation sure is depressing, but then again at the end of the tunnel is money and fame, it is only reasonable the path shall be difficult.
