I can see that this for some kind doesnt work with the current state of foss. Its basically free work for corpos.
I will therefore implement 100% agpl in my projects and make them incaccessible for anyone who tries to put into proprietary software.
The equal shares are just one possible solition and since this community is full of trolls who cant just discuss something (you and a handful peeps excluded), I‘m not really in the mood to think about this anymore. I‘ll just use the most restricted license and call it foss just to piss people off.
To your last point I dont know what the misunderstanding is. As I read it, you‘re saying the proprietary software includes a foss library. I wouldnt know or care because I bought a product not a library. My idea was for using the code not for the end user of a derivative work.
