Ehh. It accumulates. Shutting down IoT is something companies remember when they rely upon you to be stable. Or shutting down domains which was a value add to their platform.

Stadia’s death was predicted in its crib because everyone expected Google could not follow through on the idea (from the outside, it does appear Google treated the adopters decently after the shutdown). These actions lead to a death spiral. Why should I invest in a doomed platform?

The lack of ability of Google to commit to a specific length of time that they'd commit to Stadia for was baffling. If they'd just say we're going to commit to stadi for the length of the NES console generation or something, then it becomes a straight business calculation - compare x to y, where x is cost to port + on going maintenance, vs Y, expected sales over a known time period. everything has a lifespan, we don't go around telling each other we're doomed, just because one day we'll all eventually die.
