Anyone is perfectly free to charge for content that is in the public domain. Getty still provides a service. For example the ability to search, preview, or download images. Bandwidth does still have a cost.

Of course it's also fine for someone to use Getty to locate a public domain image, and then acquire it for free from another source.

Getty sending copyright notices on works they know (or should know) to be in the public domain is a real problem.

Ulysses is in the public domain. You can buy it for $2.
