Software can be commercial and open source meaning you can read the code but you have to purchase a licence to make copies and/or use it - that's open source but not Free[-Gratis] Open Source Software (FOSS).

[dragonwriter]

No, that's "source available" or "shared source", not " open source".

[jamiesonbecker]

Although FOSS has a broad definition[1], most technical people refer to Free Software by the GNU interpretation, in which the Free in FOSS is "Free as in Freedom, not Free as in Beer". FOSS is generally considered a subset of Open Source software.

You can charge as much as you like for FOSS[2].

Open Source is not the same as Source Available[3].
