@Sheril Stupid question, why is your phone not degoogled yet, and why are using ad-based apps on it?
As the article mentions, at least in some jurisdictions, that's all at least partially legal by the users using these apps.
(Those won't fly probably in places that have limits on ToS being surprising, etc)
It's a bit like complaining that the party of face munching leopards is feasting on your faces after YOU ELECTED them to office. What did you expect? Them respecting your privacy?
@Sheril These modern ad industry scum are known literally to work with criminals if it makes them money. So be happy that they didn't have yet the idea of activating the camera for better predictions, and the chance of selling some adhoc amateur porn (you signed the release when you clicked OK. Luckily for you, the US is important enough and prude enough, that porn releases require a specific form by federal law). Missed that one by sheer luck.
