These questions seem lost in ideology. The free software movement gave me an operating system and critical applications so I can do my work without big company garbage interfering.

Unfortunately there is a low ceiling to the utility of copylefted software as my experience in commercial software development shows that any commercially successful development based on copylefted software invites scrutiny such that one must constantly prove that every feature of the software can be directly linked to published source code changes. Any failure to do this can result in costly and distracting legal actions. Because this is onerous software developers who seriously wish for success and profit minimize exposure to copylefted source code. This makes it clear that freedom is a complicated business of trade offs and not a matter of ideological purity tests as the hype surrounding copyleft implies.
