>While MSYS2 is based on parts of Cygwin, Yes, this fragment is what my reply was about. >it is not Cygwin (as opposed to how, say, Ubuntu is based on Debian).

Instead, I interpreted the gp's comment as being unfamiliar with MSYS2 and how it's related to Cygwin to fill the use case for a UNIX-POSIX-emulator. Extra trivia... as for whether "MSYS _is_ or _is not_ Cygwin" is a matter of context and particular person's perspective for comparison.
