Except of course it is obvious, and the only delusion here is the farcical idea that there's some legitimate explanation for the known facts unfolding the way they did.

1. Trump has a "very good" phone conversation with Xi in which they discuss, among other things, TikTok
2. Biden announces that his administration has no intention of enforcing the ban.
3. TikTok announces that they're going to shut down US access themselves.
4. TikTok announces that they're not going to shut down US access after all, and credits Trump for saving them from a ban that was never even implemented in the first place, and over which Trump had no authority anyway since he wasn't even in office yet.

Since you've so definitely rejected my explanation for why and how these particular facts unfolded as they did, you certainly must have some alternative explanation.

So let's see it.
