Zimaboard came out of kickstarter a year and a half ago. Patience is a virtue.
Another reason why there aren't that many alternatives is that you can't use it for that much. It's like buying a car that can carry 50 kg. Great if thats your use case, but if you want anything more, there's no point. I can't really use it as a NAS, firewall etc. I think it certainly has uses, they are just ones that the average NAS/server people can do with a stronger server that can also do nextcloud, pi-hole, etc, in one, rather than have a device for each (which is way more costly).
