Most technology is a double-edged sword. Front-facing cameras on phone are immensely useful for video calls and impromptu portraits, but in event of software compromise, can disclose a lot of info. Cell networks revolutionized communication and network availability, but make all other tech omnipresent and allow rough tracking of users by signal strength.
The existence of technologies are fine, but we need to set strong social norms, laws (and resilient enforcing institutions), and smart design limitations to protect against abuse.
