It probably means that the CNNIC certs will still be valid in China, as Google doesn't directly distribute any software there directly and the Chinese government can tell the Chinese software vendors to trust its cert regardless of what google thinks.

Their lawful rights and interests will not be affected because, in the opinion of the Chinese government, anyone who uses Chrome in China is doing so unlawfully! (Last time I checked, the GFW blocked Chrome downloads.)

Except there are plenty of Chinese websites (including Baidu) that offer the latest Chrome downloads. In fact, the majority of my friends (I am a Chinese) all use Chrome and they are not software developers. Many Chinese websites are tested against Google Chrome (in addition to IE and Firefox). Put simply, people in China act as if Google Chrome were not blocked at all.

And the binaries aren't modified?

Well, the binaries from reputable sites are not modified. I just downloaded a Google Chrome for OS X from Baidu and successfully verified it with digital signature. Of course, there are also shoddy sites, but that is equally true for American websites.

The difference is that outside of China, you can get your binary straight from Google =P
