Packages being taken over because of stolen credentials creates a maintenance nightmare, and bad publicity, for PyPI itself. As such, they have every right, and a reasonable need, to require 2FA. In contrast, the maintainers of PyPI don't lose too much if a few projects choose not to use the platform anymore. Remember, you're not paying PyPI anything either, so the fact that it may inconvenience your own projects, whether free or proprietary, is not their problem.
