It is an important question, but Google services which are largely consumer-based and no cost are a very different world from Google Cloud. People get a lot of Internet Cool Guy points these days from falsely conflating the two.
I'm not the to make commitments but our history has been solid, and our deprecation policy is embedded in our terms of service for every Cloud user.
The only product I can remember us deprecating in GCP was Prediction API in favor of the much-preferred Cloud Machine Learning Engine, and with that came communication to every single affected admin and a _year_ before cut-off.
Uh, just last year Google increased the price of developers using the maps API by an order of magnitude with no grandfathering policy, which for many users was effectively shutting the API off completely.
It's not just the consumer side; Google doesn't exactly have a spotless reputation for developers, and assuming the post must be somebody faking being concerned for "Internet Cool Guy points" is just tone deaf.
