I believe it has nothing to do with competence, the hostility is pretty clear. IIRC R.hill had similar experience with Chrome Extension Store years ago. Once they want to kill your extension, they start doing this kind of stuff, at the end Google roll out mv3.
Great that they managed to find a way to bypass it.
(I can imagine that the complaint about data collection comes from the file referencing “googladservices” a lot - but that’s to filter it of course).
