Yes I think Netflix switching towards HTML5 is the biggest reason, which is helpless for me since in Europe Netflix does not work, except few countries.
I thought, more than a problem between Google and Microsoft, it was a war against Apple since Google is still developing his browser to support it, simply it gave up it for the Mac version.
