Rancher has been around a long time and isn't cloud-specific. Until this distro can prove itself useful outside of the AWS ecosystem, then Rancher will still dominate.
I liked RancherOS's very few moving parts approach (even your shell is a Docker container). Hope Bottlerocket will be somewhat similar.
I don't see any confirmation based on that link that it is abandoned. There was an update in June.
> RancherOS 1.x is currently in a maintain-only-as-essential mode. That is to say, it is no longer being actively maintained at a code level other than addressing critical or security fixes.

It looks like that link is broken and I can't find anywhere on their website that states this anymore
