Would you pay to have access to a service which tweaked the open-source software you use just enough to make it much more useful to your workflow, and automatically updated it over time? (I'm not just talking about a one-time fork; I'm talking about a subscription to get access to a maintained fork that stays current with upstream, fixes any conflicts, does the rebuild, hosts the build, etc... This justifies a cost) This incompatibility with DJI images that the Darktable devs #wontfix is a perfect example use-case.
Needless to say this would be for professional use, with professional expectations, but if your business depends on having that slightly-tweaked tool, then it may be worth it; just exploring the idea, here
There is a huge overlap between (OSS users, people who can code) and an even bigger overlap between (OSS users, people who can use coding AI tools)
The people who can't even use coding AI tools probably also use mostly closed-source software that you can't fork easily.
