In the enterprise context, I guess the Google Search Appliance would be a good example.
Before you say "it wasn't widely used" -- that's probably why it was killed. Google customers who use a product that doesn't lead its market and/or make megabucks should be worried.
We know there are other products that are failing to gain traction in the marketplace -- like GCP. While I'm not saying GCP will meet Search Appliance's fate, it has already been reported[1] that there will be financial consequences if GCP is unable to get a #2 position in the cloud marketplace by 2023.
