You've been very diligent in replying to the detractors in this thread, but I have yet to see any compelling examples.

You say that there are plenty of examples of copyleft projects being overtaken by proprietary versions that then create network effects that end up being worse for the end user because the original project was copyleft. You further assert that if the original project had been permissively licensed, this wouldn't have happened.

I'm unaware of this ever happening. Can you list a few of the examples you had in mind?
