For the most part I don't think there is a difference. It seems like once all the common factors of divisiveness and brainrot are removed, the main difference between TikTok and the others is that it would be harder for certain powers in the US government to corral TikTok into toeing the line on State Department foreign policy goals than western companies. Considering the largely homogenous, biased western media coverage of e.g. the lead up to the 2nd Iraq War, Patriot Act, US-Israel policy that has shaped American viewpoints, I don't think it is obvious why having a major non-aligned media source is a net negative.
