The business scheme is perfectly valid. It’s the same on Instagram as well.

I don’t have an Instagram account and don’t see a reason to create one, but my friends can still link me pictures or videos that I can look at. If I want to engage in any way or read past the couple top comments, I need to create an account.

Showing the user what they came for is a good way to get free advertisement, but requiring them to create an account to actually use the platform is perfectly reasonable.
