Montana has become the first state to ban the popular social media app TikTok, with the state House of Representatives passing a bill to prohibit downloads of the app and its operation within the state. The bill goes further than prohibitions in place in nearly half the states and the U.S. federal government, and is seen as a testing ground for a potential TikTok-free America. It remains to be seen whether other states will follow Montana’s lead and enact similar bans, and how the bill will be enforced and withstand legal scrutiny.
