Pre-election, it was a concern for all lawmakers that IDF soldiers showing off their genocide, or Palestinian sympathizers angry about genocide should not be able to embarass the US to young people. Congress voted to "force sale" of TikTok, and Biden signed law many months ago. Minuchin/Zionist groups offered to buy Tik Tok without the algorithm just so they could fully complete the zionist monopoly of news/media through censorship power. After the election, zionist supremacism media exposure doesn't matter anymore. US/Israel gets to do what they want to do, and explicit Trump/GOP supporters do not hand wring over Islamophobia.
Biden did say after SCC ruling, that he would not enforce anything, and Apple/Google could have avoided removing from app stores. But Tik Tok went dark anyway, with specific message, imploring glorious new leader's "progressiveness" on not hating Americans for the complete BS that was the ban fiasco. Even if bipartisan zionist congress voted for ban, with explicit justification that Israel needs to be given a better image to young people, it is flattery to Trump to make this all balmed on dark Brandon.
