I'd downvote you twice if I could. Open Source is not and never was about not making money and it was never about giving away what makes the core of your business. Github shares a lot of code and projects that are useful to the open source community [1] and at the same time provides a free service that is tremendously useful for a lot of open source projects. I feel like they're doing their part of sharing, attacking them because they're a profitable company is just cheap.
