President Obama,
Please immediately issue an executive order ending the PRISM program.
The PRISM program, as you are no doubt aware, works with companies such as Microsoft, Apple, Google, Facebook, and others to put back doors into their proprietary software and their "web services", so that government agencies can directly access data belonging to their users without obtaining a warrant.
People should stop using "cloud" services, and nobody should be using proprietary software in the first place, as it is impossible to be sure of what it really is, and what it really does.
The EULAs of proprietary software and these "cloud" services are usually designed to allow the person who wrote them to do nasty things, even without PRISM.
We should demand Free (as in Freedom) software instead.
