Earlier quoted context omitted.
That sounds like something you wish is true, not a reality. I can't think of a project left to rot that got notable bad press, but I can think of tons of cancelled ones that left sour tastes in people's mouths. From a brand perspective, rot is 100% the right call.
Google AppEngine (python variant) has been rotting forever. It's still stuck on Python 2 and has received no API improvements.
2. Bad product management / development speed seems to be the case here, not rot or killing, as it seems it's actually not stuck on Python 2 anymore, or for long [1]
3. Even if neither of the two things above were true, I have seen no bad press on GCP due to this, and I'm a heavy GCP user, though just not in this niche. I've used Python cloud functions as well as GAE though.
