Free software is not necessarily free. Even when the sources are 
released under a free software license (such as GPL), the compiled 
versions can be charged. But anyone is free to get the sources and 
compile them.

That said, MakeMKV is not a free software, and it is only partly 
open-source. It's a freeware (for the DVD rip/decrypt part) and a 
shareware (for the bluray rip/decrypt part).

Indeed yes in the case of a free software (but no in the case of MakeMKV)
