Esoteric gearing/hubs are really expensive. I have an internally-geared bike, and the rear wheel/hub is already 1/2 the cost of the entire bike... and that's more or less using tech that was originally developed in 1957.
I gave it my "throw-away" number, after going through the text code validation it spit out a relatively high score, listed my carrier as Tmobile, "no associations" in all the categories and then sent a follow-up text "Thanks for letting us doxx you!"
Between that and a crypto bro founder / CEO this seems more like a pretext to harvest mobile numbers.
Agree wording could be improved. For number harvesting, there are probably thousands of databased out there with far more info for almost free. We made an attempt to create awareness on how important your number is as in too many identities attached to it and then vulnerability against SIM Swap
