I can't imagine being one of the PMs/higher-ups that decided to allow clipboard content to be shared willy-nilly like this. Like, what must be going through their minds when they make decisions like this? "User experience at all costs?" Seems contrary to their stance on privacy.
Personally I couldn't care less about google seeing whatever junk I sometimes have in my clipboard if it means I can more quickly go to the address I'm looking for
and I'm sure there are many who couldn't care less about the malware running on their windows machine as long as they can browse facebook. What's your point?
IIRC having an address (or address-looking string) in your clipboard will cause it to show up as the first result on the search screen in Google Maps.
