This gets tiresome. Github is a lot more than a host for Git repositories. If you want to suggest that people use something else, you need to suggest a replacement that has the features people use Github for.
I think you missed the joke, which is that the parent poster you're replying to is suggesting a 'solution' to the problem which evolved in complexity until he was just describing Github again.
yeah, #1, it is free private file storage, and #2, it's a download portal for free as in beer software replacing paid offerings. that's what it is for 99.99% of people.
being a host for git repositories has never been its core competency. neither has its groupware offering.
does it even serve OSS well? a very interesting criteria is, "Have mature or adopted end-user-facing OSS recently merged a large PR from an unallied contributor?" The answer is overwhelming no. This is why there is so much innovation in this space.
Increasingly less and less so as they “upgrade” their offering and have more and more downtime.
