I don't really understand the complaint here. It seems for most of those extensions have it in their literal purpose to send the active URL and get additional information back, for doing something locally with it.

We beg to differ. Consider for example "BlockSite Block Websites and Stay Focused" why would you need to send browsing data to remote server if your job is only to block selected domains?
