The claim is substantially supported by the fetched article “Jack Dorsey’s Bitchat removed from Apple App Store in China over violations,” which states Dorsey confirmed Bitchat was removed in February following an Apple notice issued at the request of China’s Cyberspace Administration. The fetched CoinPost article independently matches the key details and adds that Apple’s notice was dated February 28, 2026. Both sources say the reason involved violations of Chinese internet service or internet information service regulations. However, confidence is not high because the strongest evidence appears to be Dorsey’s X post and Apple notice screenshot, and I was unable to fetch that original post directly in this run. So the statement is best assessed as likely true rather than conclusively proven.
