Days after TikTok users sued to block Montana's TikTok ban, TikTok has followed through on its promise to fight the ban and filed its own lawsuit in a United States district court in Montana.

"We are challenging Montana’s unconstitutional TikTok ban to protect our business and the hundreds of thousands of TikTok users in Montana," Brooke Oberwetter, TikTok's spokesperson, told Ars. "We believe our legal challenge will prevail based on an exceedingly strong set of precedents and facts."
