Containers aren't really supposed to be precious. With live-restore enabled the daemon restarts should be transparent
I have a hard time thinking of a situation where I really cared about the runtime version
I prefer automatic updates, especially something like Docker that can be a security liability. Being in the docker group is essentially a path to privilege escalation
It also gives the new stuff more road testing
Giving something to me for free and then altering that free thing at a later time against my wishes is not reasonable IMHO.
Consider an e-book: would it be acceptable to give out free e-books, then change that e-book (remotely) at a later time? What if those changes remove value? Or, what if they introduce content that you find highly objectionable?
Now, imagine a future where every (digital) thing is like that.
Docker can do whatever it pleases in accordance with its licensing, but we don't have to like it.
