GitHub, Collaboration, and Haters
While I don't really approve of the anti-sourceforge attitude, I do understand it; when SF had essentially a monopoly on open source project storage, they chose to milk it and rest on their laurels rather than improve themselves. People complained about how SF broke wget with their download portals for something like four years before SF did something about it. SF's forced review of every project creation (and their gigantic delay in doing so) had a strong chilling effect on open source project creation in general.A lazy monopoly has a way of generating extreme hatred due to the impotent rage of the people that use it because they have no other option. SF may have drastically improved in the presence of competition, but it's no surprise that some people are still angry.
