"We also explained that a fully powered-down phone should not be transmitting data to towers"

AFAIK this is not true. If you are a person of interest your phone can still be used for tracking.
This article linked below, is pretty good and includes a chapter on tracking while phones are off.
Therefore I consider the article linked above dangerously incomplete.

Pretty good breakdown of OpenAI o3's (quite good) performance at guessing locations based on photos, by way of the "GeoGuessr" game (metadata stripped). It scored better than a very highly ranked human.

A tendency of some AI critiques is to treat all such evidence as "smoke and mirrors". That is unhelpful; it occludes awareness of capabilities that are actually improving (and can present real #opsec and surveillance risks in this case).
