Seriously? You have intentionally broken your reader? Is this because you don't "like" Google? so you're going to A) victimize your users and B) force them to use other readers that are actually functional? What on EARTH are you guys thiniking - or ARE you!? What is the workaround? Where is the setting that turns thi craziness off and why is it set as a default in the first place!? I can put an event on a calendar with a link to an html page describing it and a seperate link to the Google map. There are so many ways around this inane policy that just frustrate users and force them to better solutions than PDF. What have you accomplished except to make your user base angry and push them to alternate solutions? It appears the inmates have taken over the asylum there in Lehi!
Acrobat does not check URLs specifically for Google or any other domain. You may have blocked (perhaps unwittingly when responding to some phone-home dialog) access to google.com domain. Go to Edit->Preferences->Trust Manager and check whether google.com is there and disabled. You can either remove it from the list or enable. If you just remove it, Acrobat will ask your permission before going there. If you enable it Acrobat will go to URLs in this domain without asking. Remember that ig you enable a domain all URLs at this domain become accessible without warning.
