Tariffs aren't a tax on purchasing foreign goods. I can buy as many tons of steel as I'd like in China while paying no money to the US Government (as long as I can export the money, which is a different issue). Tariffs are taxes on importing foreign goods. That would only even conceivably be comparable if Microsoft were planning to relocate TikTok to the US; as it sounds like they're planning to relocate it to London, that wouldn't apply.
