To my knowledge, a lot of these tracking and accountability applications end up in hot water because of their usage from bad actors.

I know there was an app on Android called Cerberus that was supposed to help you track your phone if it was lost/stolen, and it had the ability to open the covertly take videos/screenshots, so you could provide it as evidence to authorities.

Eventually, Google Play Store pulled the application after it became a fairly popular app for people to stalk their significant others without them knowing. I know for certain that iPhones already limit a lot of features from these types of apps. Just look at the limitations that CE admits to having when installed on iOS, including the inability to grab text messages, and only working through Safari.

The major players in tech, imo, have done a good job in preventing people in accidentally installing these applications that could invade their privacy (and instead, allow their own applications to steal your data...) It's another discussion to see how much personal data we allow big tech to access, but I can say that they've done a solid job preventing these third party tracking applications to stay on their devices. The only way they can be installed is if you agree to it being installed on your devices, or being coerced into it.

The only solution I can think that would work long-term is if people get educated on the benefits and sanctity of their right to privacy, and don't give these tracking companies any business, leading to their eventual collapse. I'm not holding my breath for that to happen, but until that happens, more and more of these stories will pop up.
