wikiwide messaged me,
his words were "3. And in mixed world of free and non-free apps the developers who make free apps don't have to trouble themselves about courts, piracy, etc - and can occasionally get some contributions and thanks for free app. While developers of non-free apps have to think about consumers, competitors, advertisement, DRM, etc - and they occasionally get some pirates and loathing from consumers. "

i prefer piracy then lack of variety..
