TikTok has been under fire for GDPR compliance, with the additional European data centres in Finland ensuring that all data from European users are stored correctly, but this has not kept the Fins from having their concerns according to Reuters, with then Minister of Economic Affairs Wille Rydman being quoted for saying that the it should be "reconsidered" on the basis of security concerns. It is worth noting that The Finnish Ministry of Defence did approve the first datacentre in 2024.
