The "and not be allowed to host content on US servers" is kinda funny as a requirement in context. Prior to the law being passed IIUC TikTok had already put in a bunch of work to make sure American data was stored in the US, with a US cloud vendor, with access controls, which were to demonstrate that this data was not accessible to the Chinese. Serving in the US, with big US cloud partner was meant to be a way to create confidence. If TikTok ends up being a webapp for US users, with our data definitely not in the US ... isn't that worse?
