Plagiarism in a whitepaper is inexcusable in my opinion. How do they expect people to take the project seriously if they cant even take themselves seriously. A half arsed whitepaper makes a half arsed project.
SUGGESTION: Contact the project moderators, update them about the error and its implications, tell them your academic qualification and you are willing to correct their plagiarized whitepaper and present it into the required standards in exchange for equity/Utility tokens. (Bounty)
Atleast this is a constructive way of trying to fix the issue.
