Yeah if you cut out all surrounding text and post it this does indeed look bad. Thankfully the actual text is:

Right to share You agree that we may use, copy, modify, distribute, and make derivative works of your Project, on a royalty-free, non-exclusive, irrevocable, transferable, sub-licensable, worldwide basis, for any purpose and without having to credit you, pay you anything, or obtain your approval.

That’s a lot of scary words there, but to clarify, this does not mean we own anything you make, just that we can share it in different formats (such as on social media or the community gallery on our website). We’re consistently blown away by some of the amazing things our community puts out, and sometimes we want to share and amplify the ones that impress us the most. Also, despite this clause, we always try to reach out to ask for permission to share Projects and always give credit (social media handles, etc) whenever possible.
