I’m of that particular age where my memories start just after AT&T was broken up into Baby Bells (to the extent that I thought “Ma Bell” was a weird shortening of Mountain Bell). So I know we’ve been here before.

Tesla’s not a great example, given that their connector is now a standard. Yes, it’ll take year for other charging networks to get built out, but that’s a temporary situation that’s a tech question. Cell service is not.
