Certainly some of this simply comes down to "how valuable is my data?".
Currently, given the extremely low (and dropping YoY) cost of storing cold data at rest, the essentially free cost of ingest, and the high cost of retrieving cold data which I almost never have to do, the ROI is wildly positive. For me.
And since all of these things (how many providers, which providers, which storage classes, how long to retain the data, etc) are all fine-tunable, you can basically do your own ROI math, then pick the parameters which work for you.
