To me this just shows how broken Congress is. US social media companies have been collecting our data, building profiles of us, manipulating us with the content they show in various ways, harming teen mental health, and all of that for decades, but Congress did nothing. Facebook in particular was used as a tool to manipulate the 2016 election by Russia in various ways, but apart from some show hearings, Congress did nothing. But TikTok is alleged to do the same thing (remember nobody has actually shown proof that the CCP is like directing TikTok to promote pro-China content for Americans), and we get bipartisanship somehow. That vote was more bipartisan than a stopgap bill to prevent a government shutdown.
And the reason is "China bad" is a message that voters agree with, and because Google and Meta are more than happy to reward these people for helping to kill their biggest rival in social media. At the end of the day TikTok users are forced onto less desirable platforms so their data can be harvested by American companies and all that, our brave congresspeople get to pretend to be "tough on China", and Big Tech rakes the profits they were losing by being outcompeted in the market. So few in Congress, on either side, have integrity.
