What an oddly aggressive comment - perhaps the problem isn't prediction but extrapolation of past experiences with Google, would you not agree that it gives you a sliver of worry that they may cut the service off?
You seem very intense about Google's offering, maybe you feel attacked by the points made in the thread, but the way you're approaching this discussion is very strange.
I'm tired of reading the same thing over and over where people prognosticate based on poor readings of events and I think people should put there money where their mouth is.
I really do not think the chance of GCP discontinuing a core service is high enough to warrant the level of comments this gets and if I find myself constantly reading these comments, maybe I can at least be compensated by people making bad bets or maybe people will admit the chance is really low.
So if you are so worried about this, please give me a number that represents how worried you are about this.
It is not a core cloud service, it is a service for a niche industry that never met the hype it had and probably didn't get many customers.
I don't think discontinuing cloud iot provides any indication that compute engine is going away.
AFAICT cloud iot core was hosted mqtt, which is a thing others offer and you can transition relatively easily. I don't think the shutdown of it was catastrophic for any companies; the quotes I saw in articles were of the sort "yeah, that's annoying, but it shouldn't be hard to migrate to something else".
Eridrus used to work at Google. Not sure if it would be good to disclose before aggressively asking people to bet on the lifespan of Google products, I certainly would err on the side of disclosing.
