The idea of politicians in the house and senate (or president) deciding which apps to ban from the app stores will likely lead to similar actions against websites, from the article:
As written, any “website, desktop application, mobile application, or augmented or immersive technology application” that is “determined by the President to present a significant threat to the National Security of the United States” is covered.
"National security" is a nebulous term that feels like an excuse to ban competitors on behalf of lobbyists at Meta or elsewhere, this is not in the interest of the majority of citizens.
