This button allows Google to know the fact that I'm currently on this specific website. If more and more websites implement this button, Google will have access to my complete browsing history!

IMO a website must ask for a permission before displaying this button.

Facebook also has a similar button ("Continue with {my_name}") that use the same iframe method.

Well FB (and Twitter) already have "Like this page" or "Tweet about this" embeds, and those allow them to track you across the Internet (or at least on sites with those buttons).
