The hilariously ironic thing is that Dunk, a Google Engineer, went out of their way to make a hyperlink of "example dot com" so that people could tap and visit the site, even where Davies' email specifically reiterates that the domain is for documentation purposes only and nobody should ever be actually visiting the site!

McCarthy of DebugBear clearly noticed this admonition and perhaps the mistake as well, because they have carefully highlighted "example.com" without linking to it, although they apparently have visited the site in order to copy and cite screenshots and unpack the CSS, and describe an extensive history of it.

What makes you think it's edited?
