In practice, US social networks usually promote content that is aligned with US cultural values and geopolitical interests. Whether this is because the government is actively leaning on them or just because being run by Americans colors them with those values, I don’t know. But the fact is, it’s not a coincidence that TikTok is the main place pro-Palestinian content was allowed to go viral, and it’s likely that changing owners would change the content on TikTok even if the law doesn’t actually require it to do so.
