I agree with the author that the GPL engenders a sharing atmosphere, and given its wild success, much more than any other license. It would be amazing if all so

I agree with the author that the GPL engenders a sharing atmosphere, and given its wild success, much more than any other license. It would be amazing if all software could be like this, but you also need to take into account how you're going to make money, and not just for subsistence, as a sustained income so people can take up a job, enjoy a decent life, and save some $ for retirement. Only a handful of high profile GPL projects, probably (wild guess) 0.0001% of the total number of projects have achieved this. Would you take up a job if you had those odds?
