Krita has a very refined process for development donations. They collect donations through a Professional funding site not a personal Patreon account and there is a clear time frame for development and a clear set of features that will be 'Finished' at the end of the development cycle.

They have successfully delivered with this model and the people who gave them money got what they paid for and will more then likely fund them again and other projects.

Can you say the same for gimp? No, someone might give some money to a Gimp developers Patreon making all sorts of promises that never get finished. The person who gave that money will probably never contribute again.

Thats a big problem for every OSS graphics project now. We have to give people who are willing to put down the money what they expected to get or they will stop funding.

Its important that the most professional, serious projects get promoted and funded to serve as a model for other projects to follow. And to grow the amount of users that feel comfortable giving there money.

You can see the same sort of professionalism with Blender and Natron development. And they also are producing quality software. If the project is fallowing this professional model then they deserve to be promoted IMO. But simply putting a bunch of promises on a personal Patreon and asking for money will do more harm then good to the larger OSS graphics community.
