Do you think the fig leaf is there for regulators or the other Android hardware manufacturers? While I agree there is no legally binding firewall (simply self-imposed), it seems there are some concerns they are attempting to address publicly.

I find Google's comments disturbing because the idea of a firewall means they have no intention of integrating Motorola. This would essentially limit any synergy between the two companies and turns this into a huge patent acquisition that comes with a side of distraction. If I was an investor, I would hope your theory of this being a complete joke is accurate since it entirely changes the lens on the transaction.
