When I first came to know about GitHub, it was a place where we find free software. Later I felt that it is the best place if you are going to code open source projects. That was true as well.
But with the GitHub Sponsor program introduced, I feel like open source maintainers are given a chance to earn money from their project without commercialising it. It is nice when we think about it. A lot of open source projects died because there is no financial motivation.
