Korea and US
I suppose no European carrier has the balls to challenge the EU the definition of 5G? Now AT&T has 5G+? They know exactly what they're doing, confusing poor old grandmothers, and stupid millenials, who are going to see that the competitors only have "5G" and they want AT&T's "5G+".
I really am surprised it's not illegal, or at least civilly actionable. Doesn't the 5G consortium have anything to say about this? If I wired up USB 2.0 and called it Thunderbolt, they'd revoke my license.
