A troll it might be, but the focus on Musk’s unconventional style distracts from a more urgent problem: the growing consolidation of online media that allows a select few of the wealthiest people and companies to control digital discourse.

With online searches dominated by Google, and Facebook parent Meta buying up the world’s biggest social media platforms to amass 3.6 billion monthly active users—almost half the planet—online discourse has centralized under a handful of corporate umbrellas.
