I do not plan on ever monetizing the core functionality of Loop, which is why I initially turned to making some of the source paid. Of course, this didn't seem to work, so Loop is now once again, fully open source :p

Currently, the only way I am making money is via donations, and it seems to be working much better than how I initially was doing, so I'll see based on how these first few weeks with 1.0 ends up.

I wish you the best. I don't think "not-fully" open source would make a difference in terms of donations. Have you looked at setting up a Patreon?

I guess that may be true. I will definitely look into setting one up!

A popular model is delayed source code release, so new features are developed on a private branch and binary releases, along with the code, and made available to supporters and then after X weeks merged into the main branch. Not sure how this would work with GPL3.
