This doesn't make any technical sense. The key part of what is at issue with TikTok and other social media companies is editorial control over the ranking algorithm. The ranking algorithm is not done on the client, and I don't see how it can be.

And even if you could do it somehow, that is in direct conflict with the other main complaint people have about social media apps ("selling your data"). FB had an API that they opened up to some degree, then Cambridge Analytica happened.
