Adding a “support/donate” button to the native application centers can greatly help increase donations to free software projects and prevent many good software from Dying : linux

I recently read an article about free software and learnt that less than 5% free software users actually pay or donate something for the projects which leads to stagnation or death of the project due to lack of funds,
I guess it is partially because its difficult for a user to actually go and fund a project directly on there site, its just tedious for them
I feel integrating a direct donation/support button to the app center can really help developers and ensure quality products in future
i think having something like this could really help entire free software community in general
(I saw this on a video about elementary os, its really a nice concept for every distro to use )
