Except you automatically own the copyright of any work you create. Copyrights do not need to be registered. So the only thing truth.social could ever actually own are pictures/words that you take from others and post without permission, and in those cases someone else probably owns the copyright. So truth.social would still not own the copyright. It really just sounds like it is just a legal catchall clause so that SOMEBODY owns the copyright in case there is a legal action.
