Installing Cygwin on a "Windows" PC is nothing an average user
could achieve easily. The _idea_ of booting something else is
also no typical approach. That's why professional companies
offer a paid service so the user does not have to invest his
valuable time in educating himself about alternatives what
he cannot do _natively_ with his "Windows". It's a simple
market decision which seems to work (or they wouldn't care
to offer it).

Furthermore, in your example using Cygnwin's dd _on_ the disk
Cygnwin is currently running from, and the "Windows" it runs
on too, doesn't seem like a very good idea. I assume it will
result in a bluescreen soon and a _partially_ erased disk.

By the way, I remember I had a DD.EXE program on my old DOS
system. I'm not sure if such a tool could operate on devices
(instead of filesystem-based representations as "drive letters"),
but it actually _was_ a DOS-based "copy & convert" utility
for the PC. :-)
