At least that’s opt-in, unlike them using your Wi-Fi SSID to fine tune their location settings. Not only was that opt-out but you had to change your router settings (either change your SSID, which isn’t hard but shouldn’t be required, or hide your network, which alienated guests when mobile data wasn’t so ever present). I don’t even know if there’s still a (simple) way out.

But yes. The option you describe is clearly ridiculous.
