Because it is extremely common to distribute an application along with
the correct version of the support packages. If I distribute a Windows
application which uses perl, I want to distribute a tested working perl
interpreter in the same package. If I distribute a Windows application
using Cygwin, I want to distribute a tested working Cygwin DLL in the
same package. Disk space and bandwidth are so cheap they're almost free.
Testing takes time.

These people already have one tested and working application on an old
version of Cygwin. Now they want to run a second application validated
against a newer version of Cygwin. As far as I can see Cygwin has been
deliberately designed to make this difficult.
