I think they've sued a few more vendors into joining since then.
My understanding is that patent-related legal services are extremely expensive. A few dollars per device is easier to deal with than months of patent research every time a manufacturer wants to change something. Especially if a company with patents has one the manufacturer wants to use.
This is not about providing a cheap alternative to patent-related legal services, it's about a dynastic enterprise using the threat of a flawed patent system against it's partners and former partners to regain lost competitive advantage in the market place!
The silver lining is still a silver lining just for Microsoft. Sales of Windows phone 7 speak for themselves (and the ODMs)
"Not getting sued" should not need to be a product.

As I said, I don't want to grade on a curve. Both of those options suck.
And as for blocking competitors, how many vendors have looked at Android and reconsidered due to the current litigation environment and imposed fees? I don't have an exact number, but I'd bet on "at least one". So, please criticize away. :)
