If it’s not killed by google, it’s replaced with a crappier version. Having developed against many Google APIs, “deprecation” is a very frequent word they use. Most of the time there is no stated reason why an API had to be deprecated, just that it is being deprecated. They also give minimal time to switch over, the worst one I had was PubSub’s API having a mandated migration we had to perform - in under 3 weeks. Very difficult for an already tasked team of engineers who had a mountain of other more pressing work. Why I actively push against working on GCP, or google products at all. I’ve successfully pushed 2 companies away from using Google cloud now.
Microsoft, as an example of the opposite, will have years long deprecation strategies, and usually go overboard with making sure engineers have a good replacement, and documentation on how to migrate. They have a lot to be hated for, but damn are they good with managing downstream engineers.
