Your first point and your last point contradict each other.

So providing the context/source = promoting it? Do you think people are going to see the descriptor text and say, “Finally!This meme made me decide to finally download TikTok!” Doubtful. Everyone and their momma (literally) knows about TikTok. It doesn’t need advertising. I think you’re doing more to draw attention to it and thus Streissanding the thing anyhow.

Please explain how this is promoting TikTok.
