A court used an app called Covenant Eyes to surveil the family of a man released on bond.
“This is the most extreme type of monitoring that I’ve seen,” says Pilar Weiss, founder of the National Bail Fund Network, a network of over 90 community bail and bond funds across the United States. “It’s part of a disturbing trend where deep surveillance and social control applications are used pretrial with little oversight.”
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.
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.
