They haven't really pulled the rug out for anything on Google Cloud (there've been a few things replaced, e.g., the old Master/Slave datastore on App Engine.)
And while this doesn't have an deprecation policy applicable as a Beta feature, most GA Google Cloud features have a one-year deprecation policy, so even if they were retired, no one would have the rug pulled out.)
You seem to be confusing Google Cloud Platform with Google services. AFAIK there have been no GCP features removed after they have gone into General Availability.
Bet hey, keep the uninformed meme going if you like.
