 ## WARNING
 
 * All forks must respect [GPLv3](https://www.gnu.org/licenses/gpl-3.0.html). Please report violations in Issues or [confidentially](https://austinhuang.me/#hey-you-look-cool).
-* Although publishing a fork is allowed by license, it is strongly discouraged to do so as it divides the effort and creates confusion. It is, therefore, recommended to send a pull request back to us, so that the larger community can enjoy your improvement. (This does not apply if you're adapting this app for a different platform other than Instagram.)
+  * Some people have asked me about publishing a "commercial" fork that serves ads. However, if you do properly comply with GPLv3, users would realize that the original non-commercial version exists and, in turn, abandon your fork. And if you don't comply, you get copystriked.
