Facebook has once again eschewed a direct request from the UK parliament for its CEO, Mark Zuckerberg, to testify to a committee investigating online disinformation — without rustling up so much as a fig-leaf-sized excuse to explain why the founder of one of the world’s most used technology platforms can’t squeeze a video call into his busy schedule and spare UK politicians’ blushes.

Which tells you pretty much all you need to know about where the balance of power lies in the global game of (essentially unregulated) U.S. tech platforms giants vs (essentially powerless) foreign political jurisdictions.
