In a way, you're right. However GitHub's model is subscriptions fund the free yet small open repositories whereas SourceForge's model is advertisement (I can't find a way to on SF though).
So naturally, GitHub had to appeal for subscribers. While for SF, I always thought ads was stupid due to the educated demographic that would likely have adblock.
