<i>"Google does at least say that these conditions are solely for “the limited purpose of operating, promoting, and improving our Services, and to develop new ones,” but as terms of service can change, I’d be a little worried about this claim."</i><p>Er, you could say "as terms of service can change, I’d be a little worried" even if the <i>only</i> term in the ToS was "these terms of service can change". If the problem's only a problem if the ToS changes, then it's not a problem yet.<p>Well, aside from the problem of the whole notion of ToS/EULAs being completely unsuitable for the way they get used nowadays. But that's a whole other issue, and has nothing to do with google.
