It is a bit unfair to call it "mislead", after all what they state is factual. It is just not very clear, and looks scarier than what is actually happening.

They just should be aware that an average user will spend 5-10 seconds maximum looking at that notice - and after that the user will delete the extension and leave a 1 star review. Which is somewhat unfair.

Thanks for taking your time to dig into the issue.
