All good points, but remember that this blog post was written for people who know as much about OSS as I know about non-ferrous oxyacetylene welding. Some of the information is superficial, but too much detail can overwhelm someone. It leaves out a few things, as you have noted, but nothing is exactly wrong. When I'm teaching Medline to medical residents, I start out with simple searches and leave "(((renal or kidney?) adj2 disease? adj2 chronic) or ckd).mp" for later. And Koha *is* a lot like free beer: spend too much time at once with either and you end up bleary-eyed and unable to walk in a straight line.

No matter how fast light travels, it finds the darkness has always gotten there first, and is waiting for it. --Terry Pratchett -----Original Message----- From: Koha [mailto:koha-bounces@lists.katipo.co.nz] On Behalf Of Narcis Garcia Sent: Wednesday, July 18, 2018 1:37 PM To: koha@lists.katipo.co.nz Subject: Re: [Koha] Chat: very good description of Open Source software This blog's article introduces serious confusions about FOSS movement. Table reflects poor study when classifies Linux (and not GNU) as an operating system, while Android is Linux-based too. "Open source" only means consumers can see the design. Nothing more about freedom. Many JavaScript programs can be understood as Open Source while them are proprietary-licensed. "Proprietary software is created and sold by a corporation" -> Same as RedHat Linux, Virtuozzo, QCAD, etc. (all FOSS) "Open source software (OSS) is created by a community of software developers (programmers)" -> Most of OSS and FOSS programs are created by a single person per project. With the 4 enumerated freedoms it tries to simulate equality between OSS and FOSS and "free as in beer".
