What's likely happening here is that people are renting VMs and one-line some docker-compose up thing from a tutorial. And because it's a tutorial and people can't be bothered to tunnel their own traffic, most likely those tutorials are binding on 0.0.0.0.
Plenty of ways to footgun yourself with c/p something from a tutorial, even if you somewhat know what you're doing. No need to bring "everyone thinking they can code" into this. This is a tale as old as the Internet.
Another thing is that docker, being the helpful little thing that it is, in its default config will alter your firewall and open up ports even if you have a rule to drop everything you're not specifically using. So, yeah. That's probably what's happening.
