I had a problem yesterday where I had so many docket images laying around from builds that starting a new container pegged my CPU at 100% and slowed everything in a docker container to a crawl.

A colleague predicted the problem and I learned about one more bit of random fragility that exists in today's ecosystem.

$ Docker system prune

It makes as much sense to complain about Docker because you let images accumulate in your system as it would make to criticize file systems because you never emptied your system's trash bin.

My file system doesn't peg my CPU when it gets 10% full.

Why the hell should the very existance of unused docker images cause the single image I am using to peg multiple cores?

And no warning was given. Heck if my hard drive gets close enough to full that it's gonna be a problem my OS tells me.
