The Chrome V8 JS engine is designed to be entirely compatible with
the
Safari Nitro/Squirrelfish/KJS/whatever its called engine. Arguably
Apple's
trying to break the open web with endorsing of h.264 as html5 video
and
marketing vendor-specific css additions as part of the standard.
Ian Hickson writes and edits many of the w3c standards. Look at the
HTML5
spec page (
http://dev.w3.org/html5/spec/Overview.html). On the header
is the list of editors. Google is demonstrably working with others in
making
the w3c standards.
Chrome isn't even close to a majority share. Assuming that you are
right
about everything else, Chrome still is not nearly in the position to
hurt
the development of the internet. Google, if not anything else is
promoting
the competition in the web-space by their sheer presence.
