I use GitHub for my public repos, but use Visual Studio Online (poorly named, since it is not actually Visual Studio) for my private ones (also unlimited, but free.) I know a lot of others that use Bitbucket, etc because of GitHub's pricing. I feel like GitHub would make more sense to smaller devs, like myself, if it were bundled with other services. Like, if they partnered with Microsoft, Google & Amazon and offered some sort of bundling packages with their cloud services. I don't know, to me GitHub...from a small dev perspective only makes sense to share things publicly. I'm sure this new pricing model will help push some smaller devs onto the platform, but it's hard to compete in that space when you have others providing private repos for free.
