dockerd is 96M and has to run all the time. You can't use docker without it running, so you have to count both. docker + dockerd is 131M, which is over 3x the size of podman. Plus you have this daemon running all the time, which eats system resources podman doesn't use, *and* docker fucks with your network configuration right on install, which podman doesn't do unless you tell it to.That's way fat as far as I'm concerned.
As far as corporate goes,
podman is free and open source software, the end. docker is a company with a pricing model. It was founded as a startup, which suggests to me that, like almost all startups, they are seeking an exit and if they ever face troubles in generating that exit they'll throw out all niceties and abuse their users (see Reddit, the drama with spyware in Audacity, 10,000 other examples). Sure you can use it free for many purposes, and the container bits are open source, but that doesn't change that it's always been a corporate entity, that they can change their policies at any time, that they can spy on you if they want, etc etc etc.That's way too corporate as far as I'm concerned.
I mean, all of this might not matter to you, and that's fine! Nothing wrong with that. But you can't have an alternate reality--these things I said are just facts. You can find them on Wikipedia or docker.com for that matter.
