@amerika >I'm a free market guy.
A situation where the government says that you can't share software without a license doesn't sound like a free market to me.

>Nothing says you could not hand out source code with your shareware or freeware except that for most people disk space was still very limited.
Merely because the source code is also available doesn't make software under a proprietary license not proprietary; https://www.gnu.org/philosophy/free-sw.en.html#four-freedoms

I don't believe disk space was the main reason why source code wasn't available, as even since when disk space became plentiful, very little freeware or shareware has included the source code.
