I’m still hazy on how open source it really is. Even if you ask it, it will tell you v3 is, and I quote “not open source”. There is a github repository so there is some code available, but I get the sense that open-source is being used as a bit of a teaser here and that for-profit licensing is likely where this is headed. Even if the code was fully available, I suspect it could take weeks to find the censorship bits.
