Free or Open SourceFree Software FoundationRichard
Stallman• Software patents are dangerous to software developers
because they impose monopolies on software ideas.• Free software as in free speech, not free beer
On Open SourceRichard Stallman
• Open source is a development methodology; free software is a social movement.
On patent trolls, Feb 2013Barack Obama
•The folks that you’re talking about are a classic example; they don’t actually produce anything themselves. They’re just trying to essentially leverage and hijack somebody else’s idea and see if they can extort some money out of them.

Free softwareA program is free software if the program's users have the
four essential freedoms:
The freedom to run the program, for any purpose
The freedom to study how the program works, and change it so it does your computing as you wish.
Access to the source code is a precondition for this.
The freedom to redistribute copies so you can help your neighbour
The freedom to distribute copies of your modified versions to others.
Access to the source code is a precondition for this.

No free trips to Redmond or …Sales
• There’s no such thing as a free meal
No-one ever got fired for buying …Risk
