Imagine replacing your Internet Service Provider (ISP) with a middleman that says, “Trust me — I won’t look.” That’s the essence of a VPN: instead of your ISP seeing your browsing, the VPN can. In theory you’ve swapped one watcher for another with better manners. In practice, you’ve simply moved the power to a new gatekeeper — and some of those gatekeepers don’t play fair.
Here’s the snap-turn of reality: running a global VPN network is expensive. Servers, bandwidth, maintenance, legal teams — the bills add up. Companies that promise “free” or suspiciously cheap services sometimes pay those bills not with honest revenue, but by monetizing users. They can log which sites you visit, who you communicate with, and even inject ads. A “free” VPN’s business model can quickly become: you are the product.
