India is absolutely right in banning TikTok as it is a significant national securities threat. As long as the platforms recommendation and ranking algos are a black box, there is no guarantee that China isn’t conducting misinformation campaigns via the platform. At the very least, the government should audit the algos and make sure China can’t arbitrarily alter ranking results.
Honestly, I don't see the difference between TikTok and other social media apps and the old media. Why not ban Hollywood, the Beatles, and McDonald's then? Aren't they a source of pernicious American influence on this generation's youth?
Many countries have broadcast laws around a maximum amount of foreign programming (for one example amongst many, private French radios have to play French music for at least 40% of their programming).
