 Free Software / Open Source 

In many articles you show your intention to use the phrase ""free and open source"". 
The best way to deal with this is to choose the term used by the developers of the programs in question themselves. If you are working on a page about a program where the developers explicitly use that term I have no objection. If the developers use ""free software"" it is best to use exactly that for that specific program. If the developers of a certain program use only ""open source"" and the license of the program is indeed an open source license (Excluding the GNU GPL. Its text explicitly uses the term ""free software"") then it's ok to use that description. 

The purpose is that the reader should not understand the word ""free"" to mean ""gratis"" in this case. Unfortunately just using ""free"" alone makes it more likely that people will understand ""gratis"".

If you software into that phrase ""free and open source"" something like ""open source and free software"" it would be better.
