Explain why more clearly why the four freedoms must apply to
commercial activity. Explain why the four freedoms imply the freedom
not to run the program and the freedom to delete it, so there is no
need to state those as separate requirements.

We want to invite everyone to use the GNU system, including businesses
and their workers. That requires allowing commercial use. We hope
that free replacement programs will supplant comparable proprietary
programs, but they can't do that if businesses are forbidden to use
them. We want commercial products that contain software to include
the GNU system, and that would constitute commercial distribution for
a price. (追記ここまで) Commercial development of free software is no longer
unusual; such free commercial software is very important.
