There's two sorts of developers reactions to Microsoft purchasing Github.
The first is pleased that GitHub will be funded for the foreseeable future. They're willing to go along with the status quo until it no longer suits them.
Then there's the developers who see themselves as part of something greater. They're the ones who want to help build better futures and see companies like Microsoft as anathema to that goal. They rebel against corporate control.
Color me part of the rebels.
