I've been reading a lot about this problem specifically with respect to Chinese culture. Insofar as we can say any one thing about a national culture of more than a billion, on the whole, the Chinese simply don't care about attribution, copyright, or plagiarism. It is the view of most folks that it's acceptable to copypaste blocks of content from one thing into another and then call it your own. For anyone else interested, the Academia Stack Exchange is actually one of the best and most interesting places to find real-world stories of people grappling with this problem, and offers some deconstruction in the comments/answers.

Oh my gosh, did they just straight up steal (copy and remove attribution) from TitanDB?

That has to be the death of this project right now, right? How could they ever monetize? DataStax (who probably owns those copyrights now after having acquired Aurelius) would probably take the acquirer to the cleaners.

And honestly, shame on them. Worst sort of open source behavior...

edit: as someone points out it might be a team in Baidu, too.

Would this commit not constitute a violation of the original licensing for the code? Attribution is often a requirement for use.

I don't think it's OK... It's a ripoff of Titan Graph. I think Datastax picked up that team to work on a cassandra specific graph db.

DSE does a lot of "team acquiring" but then the open source projects get shuttered/killed off. Which is kind of crappy.
