The reality is that apps like TikTok, Twitter, Instagram, etc.. have marketing teams and entire institutions practically advocating for their use across the planet. In some parts of Asia and South America, you literally cannot get by without WhatsApp in more urbanized areas, for example.

This is the result of US imperialism. They have just enough data centers and server capacity to run hundreds of Instagrams if they wanted to, unlike the Global South (excl. China).
