If China was going to use TikTok as a weapon... wouldn't now be the time?

Some have been saying how TikTok could be used a a psychological weapon... (either with content being pushed to destroy our minds or sometimes of tech within the app to disrupt someone . mind while they are watching it...

IF that is the case, wouldn't now be the time for use a weapon to be used? Trump has just increased tariffs on China , the app is banned from app stores so they don't even have to verify the integrity of the app with them... and it's still downloaded on millions of devices. Plus they are being forced to sell to an American. Seems like IF it were a weapon; they would use it right before being forced to sell.

Question is... it it possible for such tech to exist that could be a psychological weapon that could be fired at once and everyone using the app is mentally incapacitated?
