Can you share public resources that you do not own?

The assertion that you can only share resources that you own reflects a misunderstanding of intellectual property laws and the concept of public resources. Resources in the public domain are not owned by anyone and can indeed be shared freely without restrictions.

Public domain materials include works for which copyright has expired or works that were never subject to copyright. Examples can include classic literature, certain government publications, and other materials that have been explicitly released into the public domain. Therefore, if a resource is in the public domain, sharing it does not infringe upon anyone's rights, as no ownership exists over it.

Additionally, sharing resources with proper permissions, as would be indicated in another potential answer, is also a valid practice, since permissions allow individuals to share resources legally, even if they are not the original owners. This means that stating you cannot share public resources because of ownership issues is incorrect in contexts where public domain applies or where permissions have been granted.

In summary, the ability to share resources largely hinges on the ownership and rights associated with those resources, particularly in the context of public domain works and permissions granted by copyright holders.
