Yea, likely they will come here with the same excuse and will blame their writers. That will prove the team's irreversibility.
The same thought crossed my mind when I strolled through their litepaper and crosschecking them with the plagiarism checker, that if only they added bibliography on their last page, their action will be justified --I even checked their last page to see if they did this, which unfortunately they didn't. Nonetheless, the plagiarism of abstract can hardly be acceptable. Copying definition --with proper citation-- and description of things from existing media is acceptable, copying an abstract, though, is something that's entirely different.
