So I wouldn't worry them killing these ala the spotify car thing.
[edit] and there's no buying the watch WITHOUT the Fitbit Ace Pass data plan, the watch setup REQUIRES a data plan.
from the Compatability section of Tech Specs page:
"Requires Wi-Fi and Fitbit Ace Pass data plan for setup."
[edit2]
though I guess you could buy just one month of the data plan, just for setting up the watch.
But the watch's WiFi supports only 2.4GHz.
[edit3]
the annual data plan deal is only good until before Aug 31. see https://www.youtube.com/watch?v=xzDpo1t02yA&t=275s
My bet is Google EOL.
If this lasts as long as Stadia it will shut down on Thursday the 5th of August 2027.
