Its pretty pathetic that american companies cant compete with tiktoks social media dominance (because they are too busy optimizing for maximum ad engagement over user experience) and so are trying to engage in a xenophobic propaganda campaign instead of just giving some product managers the power to override decisions by the ad dept.

Instagram has a horrible ux, and they accept that because they'd rather chase dollars than user satisfaction. There is no moat around tiktok, it's just stubborn hubris.
