I do hope we¹ can figure it out, too.

There’s a middle ground solution here. TikTok does (naturally) have a version of each video without watermarks which they show in-app. They don’t let you download it, but external tools can generally help with that. What Loops could do is default to a watermarked version, but allow downloading original as well. This way, person sharing the video can decide whether they want to help promote Loops or not.
