@joethephish@mastodon.gamedev.place I've no idea how successful it was, but Dan Simon actually did this when he created the HERODesigner software (herogames.com/store/category...) for the Hero/Champions #ttrpg.
You can pay for the app, which is obviously what most people do, but you can also pay for the source code to modify the app with your own house rules etc.
I honestly have no idea at all how many copies of the source code were sold, but it was definitely interesting to see this model being tried out 'in the wild'.
