Question is if this extension detects having changed owners itself? Maybe something else, not an extension, would be better suited for that kind of check, although of course more complex I guess.

Yep. Maybe a website that tracks them and sends email or other notifications

Creator here. It does self-detect (chrome.management.getAll() returns all installed extensions), but fair point.

This is how you make an extension that you can resell for big bucks. People looking to buy extensions will need to buy popular extension checkers first so they can do so undetected. /s
