So what's magical about Safari?

[Joel Harrison]

It occurs to me that Safari may also refuse to accept the opt-out
cookie, which would mean that Safari users would have no way of
preventing their data from being scanned.

On reflection, that may be why the reference to users' data not
passing through Webwise was deleted - it suggested Safari users got
more protection than they actually do.
