What doubletalk. If usage restrictions were in *any* way what end users
wanted, they'd choose software that has it over software that does
not.

Usage restrictions serve *no* want of the end user.

This need is adequately served by not imposing usage restrictions. Any
effective imposition of usage restrictions is hostile to the wants of
the user.

If usage restrictions are brought into the picture, it is to serve the
wants of someone else, *not* the end user. It is disingenuous to
suggest otherwise.

This is describing a want of the copyright holder, *not* the end user.

Very sound advice, I agree entirely.
