On Tuesday, a bipartisan [!!!] group of lawmakers introduced a bill that would give TikTok owner ByteDance a deadline to divest itself of the social-media platform. If the law passes and the deadline is not met, the app could face a ban. On Thursday, some TikTok users opened their apps and encountered this message:

Speak up now — before your government strips 170 million Americans of their Constitutional right to free expression.

This will damage millions of businesses, destroy the livelihoods of countless creators across the country, and deny artists an audience.

Let Congress know what TikTok means to you and tell them to vote NO.

This is surprising but not unprecedented. When facing potential regulation, Facebook, Uber, Airbnb, and many other apps have asked users to lobby on their behalf; TikTok itself has previously made its case directly to the public too. Most of the time, these sorts of things are easy to ignore, and most people do — you tap a little x, or hit the back button, and scroll on. Except when you can’t:

When I opened TikTok today, I got this pop-up that gives you no option to exit or swipe away, the only action is to “call now”
