I think if more people were aware that their "Atomic Clock" wasn't going to be keeping the correct time anymore that lots of them would be scampering to the petition to sign it. There's still a lot of people using alarm clocks in the morning. Lots use their smart phones, but we, like most likely many families, use regular alarm clocks, too. I can't remember the last time I set the time at the small digital clock beside my bed...I don't even think about it anymore.
We get very, very poor cellphone coverage at our home, whether inside or out, but inside being very, very poor. I get no cellphone signal in my bedroom at all. But, that little digital clock sitting on my nightstand stays set perfectly via the WWV signal.
Yeah, if more people knew, more people would sign.
