How the Hell Are These Popular Spying Apps Not Illegal?

(a long and excellent article)
Here are some sordid scenarios. Your ex-girlfriend can see every time you swipe right while using Tinder. Your former husband is secretly listening to and recording your late-night Skype sessions with your new boyfriend. Some random slippery-dick is jacking off to the naked photos in your private photo library. For millions of people, it's not hypothetical. 

Someone could be spying on every call, Facebook message, snapchat, text, sext, each single keystroke you tap out on your phone, and you'd never know. I'm not talking about the NSA (though that too); I'm talking about software fine-tuned for comprehensive stalking—"spyware"—that is readily available to any insecure spouse, overzealous boss, overbearing parent, crazy stalker or garden-variety creep with a credit card. It's an unambiguously malevolent private eye panopticon cocktail of high-grade voyeurism, sold legally. And if it's already on your phone, there's no way you can tell.

Spyware companies like mSpy and flexiSPY are making money off the secret surveillance of millions of people's devices. Literally millions of people, according to the sales figures provided by these spyware companies, are going about their days not knowing that somewhere, some turdknockers are scouring their photo libraries and contacts and WhatsApp messages, looking for digital misdeeds.

Spyware has been around for decades, but the current crop is especially invasive. They make money by charging people—from $40 a month for a basic phone spying package on mSpy up to $200 a month on one of flexiSPY's bigger plan—for siphoning activity off their target's devices.
