Reddit Inc owns that content.

Not true. From the User Agreement linked in the footer of every page (emphasis mine):

your content

You retain the rights to your copyrighted content or information that you submit to reddit ("user content") except as described below.

That means the content you submit is still your property. It goes on to say:

By submitting user content to reddit, you grant us a royalty-free, perpetual, irrevocable, non-exclusive, unrestricted, worldwide license to reproduce, prepare derivative works, distribute copies, perform, or publicly display your user content in any medium and for any purpose, including commercial purposes, and to authorize others to do so.

That does not transfer ownership of your content to reddit. People have pulled their content from other sites in the past because they thought such language had such an effect. The reality is that every single website that hosts user-created content has (or should have) such language in their agreement, because it would be illegal for them to host their users' content otherwise. That paragraph just says you give permission to reddit to display what you submit on their website (which is what you submit it for, right?) as well as in other media (e.g. the Upvoted podcast).

If you don't believe me, reread the quotes from the agreement.
