The authorities cited national security concerns and warned that using VPNs to bypass the block could lead to legal penalties. Further actions included the October 2024 suspension of Mwananchi Communications Ltd.’s online platforms for 30 days, following the publication of content deemed threatening to national unity. Additionally, research by the Open Observatory of Network Interference (OONI) documented the blocking of numerous websites and applications related to LGBTIQ issues, including Grindr, between January 2023 and January 2024, as well as restricted access to VPN services, Clubhouse, and 4chan.
