> what's the incentive for authors of one-man projects to choose anything "permissive". The incentive is generally that people enjoy having their projects used, be that by commercial companies or otherwise.
(A)GPLv3 does not prevent their projects from being used. That's the point! GPL family of licenses would've made a difference in this aspect for libraries (because afair if you link to GPL code, you must be GPL). But for an app? You can use it, fork it, modify it... Just make sure you make your changes available under the same license. Seems very fair to me.
In practice, it does in many cases. Many companies have a blanket policy of avoiding these licences. But I agree that they make more sense for apps than libraries.
