Can't believe the sense of entitlement in this thread. I guess people think bandwidth grows on trees.
For residential usage, unless you're in an apartment tower where all your neighbors are software engineers and you're all behind a CGNAT, you can still do a pull here and there for learning and other hobbyist purposes, which for Docker is a marketing expense to encourage uptake in commercial settings.
If you're in an office, you have an employer, and you're using the registry for commercial purposes, you should be paying to help keep your dependencies running. If you don't expect your power plant to give you electricity for free, why would you expect a commercial company to give you containers for free?
