What do you mean by copycat? As in he takes someone else's paper and gives it a clever name? Or do you just mean he is using lots of silly methods of doing data exfil?
The author is clearly an expert in exfiltration and has deep insights in the area. But instead of working on presenting the big picture, prefers to throw breadcrumbs to the community. After a dozen of "exfiltration using X" papers, one would at least expect an SoK paper.
If the answer was "we tried really hard, but couldn't figure it out" pretty sure the paper would not get published.
If it was so trivial other people would be doing it.
