Microsoft inspired and/or supported?
It was inevitable that Patent Trolls would go after OpenStack organization itself, and not after IBM, Oracle, RedHat, HP, Dell or any other of the very large and wealthy commercial users and strong supporters of OpenStack technologies, that are overwhelming the Microsoft Azure Cloud Computing effort, with far superior features, functionality and efficiencies of cost.
This type action bespeaks the very devious and sinister characteristics of Patent Trolls, especially the draconian "Rockstar group", started by Microsoft with Apple, Sony and other heavy Free/Open Source Software (FOSS) users litigating, most likely illegally and unethically, against their own interest and economic benefit.
Such is the nature of excessive greed in the unscrupulous and sick capitalism that permeates every level of business in USA.
