Podman just makes more sense because it doesn't require a big fat daemon. You launch containers like any other service: with systemd. And you can run podman without root permissions as well, which is a huge win for security.
More important, I only saw RHEL at traditional Fortune 500 companies. Not sure how their market in FANG type companies is. Probably negligible. F500 is still big of course.
There are two distributions left in Linux, RedHat derivatives and Debian derivatives. In terms of install base, it's maybe 1/3 and 2/3. In terms of money, expect the other way around, because it's F500 who pay the most for software and they are on RedHat.
RedHat is actively trying to kill docker (along Google and Amazon). RedHat removing "docker" CLI and replacing it with its own tools is a major step toward that. Docker will be de facto dead in enterprise as soon as it stops being supported by RedHat.
There is nothing that prevents RedHat to ship an alias to their own tools by default, just like java => openjdk.
It's not the responsibility of RHEL to maintain or support third party software. If case you didn't know, docker stopped shipping with Debian years ago.
The day RHEL customers stop using the docker runtime is when RHEL will stop supporting it - until then, they'll support it. Case in point: java -> openjdk.
Anyhow, this article is just click bait, and it's been done at least twice a year since Dockers inception. I'm disappointed that this community finds shitposts like this more compelling than the NSA opensourcing a reverse compiler, but I digress.
Have fun in your bubble.
