You should have seen two different screens to opt-out of Chrome.
The first during the install, the second after reboot.
Personally I would prefer it would be “opt-in” and not opt-out.
As users we are seeing more and more bundled software.
The end result is that the end user must be ever more vigilant
and not just click, click, click their way through any install.
Doing otherwise could lead to unwanted software, toolbars and even changed homepages.
