A thing never mentioned in these debates is that noone in the world is buying tiktok without buying the underlying algorithm, the same algorithm the app runs on worldwide, the algorithm is the special sauce. They are not going to sell the basis for their app just for a single payday in the US market, which after buying it, they could rebrand and then once successful in the US, compete in the global market against tiktok but with the income of the most lucrative app market in the world behind them. It’s an extremely stupid business move.

They're probably going to find themselves having to explain what it means that a social media platform is itself engaged in speech, instead of functioning as a platform for others to speak. TikTok users, whose voices are allegedly curtailed by the ban, aren't exactly prevented from going to another platform.

If they say that it's Tiktok's speech that's curtailed, they're going to have to explain carefully how they're not a foreign influence operation.

The language of the first amendment is pretty stark, but the courts have always understood it has various limits.
