On what basis does it make Google untrustworthy? Was there some kind of announcement that this service would run forever? Or was that simply your expectation?

It's important to differentiate between what other parties are obligated or have promised to do, and what you want them to do. Failing to deliver on the latter is not a violation of trust. It's like saying someone you dated is untrustworthy because they decided to break up with you and they didn't find you someone new to date.
