It's unnecessarily complicating things to require case sensitivity here. Words don't typically completely change their meaning just because of capitalization. And suppose I write that in a Slack channel where no one uses caps at all? Do I have to use caps anyone to make sure I'm not confusing everyone? How do I pronounce it correctly if I'm giving a speech such that listeners know which one I mean? What if the closed captioner writes the case wrong?

Nah. "Open Source" = "open source", because any other interpretation goes against the norms of written and spoken English, and because it'd be an absolute freaking pain in the neck to create that brand new distinction that's not an issue today.
