> I implemented a new feature: the ability to upload texts automatically, in background, without user intervention. > I had, unknowingly and unwillingly, built a spying tool, and a really convenient and efficient one. > Thanks to background uploads, people could install the YouArchive.It app on another person’s iPhone, set it up, maybe even hide it (something possible on a jailbroken iPhone), and then watch as the text messages come in, almost real-time. Jealous partners, stalkers and the likes could install this tool on an unknowing victim’s phone with relative ease. ... This hit home: (The absolutely otherwise fantastic) NextDNS (and anything that's similar to it) comes pretty close to a spying app, too (300,000 DNS requests per month conveniently stored for a long time, for free). I know a handful people who I introduced NextDNS to as a privacy enhancing service ended up using it to encroach upon privacy by configuring it on unsuspecting user's Android and iPhones (doesn't even require jailbreak or root and runs forever in the "background").
