You kind of have to wonder about why it didn't work out and become more popular to keep the product around.

Then again, i feel the same way about Intel Atom and most other low-power offerings - it puzzles me that they never got big.

Having low cost/high density options for hosting stuff online would be pretty great. After all, lots of people already run Raspberry Pi clusters at home.

I'm very open to corrections, but from what I recall of it, it was extremely custom to them, in terms of hardware, and seemed experimental. I suspect the logistics of managing a lot of custom equipment that wasn't making big money (as Amazon does with Graviton) wouldn't have been super appealing long term.

I had the same impression. For a turnover of 50 EUR per year and instance it was hard to see (for me as a complete outsider) how it could be an interesting business. Amazon charges more (as usual...), I know even less about their hardware.

The advantage Amazon has is that their hardware isn't really their USP whereas those Arm devices were for Scaleway at the time. While AWS does make a song and dance about Graviton (and quite rightly, IMO) AWS can really develop and shuffle in whatever tech they want behind the scenes as long as it runs customer workloads.
