For me that's a naive stance that ignores the problem of corporate influence on politics.
Apart from that, how is US corporate influence necessarily better than foreign corporate influence? Neither care about the US general public. Some US companies knowingly harm their own citizens (Philip Morris, Exxon, Purdue, etc.)
One can argue the problem with TikTook is that it's controlled by the government of an adversary nation (from the viewpoint of the US), but it's not just the fact that the company resides in a foreign country.
