Return Youtube Dislike’s developer here. Extension that keeps dislike counts “in parallel” to YouTube’s official like and dislike count.
Situation is similar to Ajay’s - all we receive from the users are randomly generated usr IDs and videoIds. We didn’t go as far as K-Anonymity implementation, but still, I consider the extension to require close to bare minimum information.
Yet the message my users receive after I’ve filled the disclosure according to guidelines is on the screenshot. The reaction is abysmal, calling my reviews section a shitstorm is an understatement. People are sure that I’m stealing all their data from all websites (despite extension only having access to YouTube).
