I sympathize with better default privacy settings too, however you must note that they didn't ask you to remove all references to Ubuntu: They only ask you to remove the logo and the domain name. You can understand they need to make it clear in the cinsumer's mind what belongs to the official sphere of Ubuntu and what doesn't. Also, before saying they're using it against privacy, we should check whether they've asked to take down similar domains with no correlation to criticism or privacy, and they answer is probably yes.

As kcorbitt says, the trademark law requires ongoing enforcement or the owner will lose the legitimity. Have you checked whether they'd let you keep talking about Ubuntu? IANAL, but wouldn't it be correct to keep a website named "Fix Ubuntu" in a domain name such as privacywatch.com? This way they keep the integrity of the brand for the consumers and you stay in the ecosystem.
