There is no possible way to prevent a user agent running on the user's behalf
from doing whatever the user wants it to do, including adding annotations.

If the user installs software without knowing what that software does, there is
nothing we can do about that. The software can't know whether the user knows
about what it does or not.

There is no way to stop this.

It is in fact for technical reasons; there is no way technically for Yahoo! to
affect the contents of a page at a URL it does not control.

Only the user agent's own software, or software on the user's network (e.g. the
library proxy server) can change the page, and those tools can change the page
regardless of what we put in the HTML page, there is no way for the originating
server to stop this (and nor should there be, since that would mean that it
would prevent users from doing what they wanted to the page).
