> I would have expected the essential share-alike fairness of copyleft to resonate more.
I have so much to say on this topic I could write a novel, e.g about commercial artists versus those who just want their art to be seen versus art commissioned with money obtained elsewhere. But in the most simple terms, at least with me, is I prefer to write and to use software with as few restrictions on/from others as possible. Can't feed my family on that of course and wouldn't try. If public domain were more accepted than MIT, I'd do it, but for now I just slap MIT on it and move on. If you make a million dollars on it, keeping changes hidden or not, good for you. I'm trying to do the same in my day job, the primary code of which is of course closed.
As for the prevalence of restrictionless licenses on non-hobbyist software, you can attribute that to their stewards simply recognizing the value of hobbyists working with it (the company reputation gained, the influence, bug finding, etc). People want fewer restrictions, companies want people.
