tytanick,
Thank you for the very thorough explanation and details. I think it's important for people to know explicitly what is extracted. It is similar, albeit different, to the concerns of using closed-source software. I think most users of the platform are not going to care even if private information is sold for advertisements, but I thought someone should point out the risks. For example, location (country only) for purposes of your accounting is one thing; location for some other purpose would likely be bad.
Thank you tytanick, and thank you for promoting the PoW ecosystem.
