Do you actually need a VPN?

The marketing case for consumer VPNs rests largely on a threat that has substantially receded. The classic warning about hackers intercepting your data on coffee shop Wi-Fi assumed unencrypted connections, and today the overwhelming majority of web traffic uses HTTPS, which encrypts content end to end regardless of the network. A VPN does hide which sites you visit from the network operator and your internet provider, and it masks your IP address from the sites you reach. But it does not make you anonymous, does not stop tracking through cookies and browser fingerprinting, and does not protect you from phishing or malware.

The honest framing is a transfer of trust. Your traffic still passes through somebody, and with a VPN that somebody is a company whose business model, jurisdiction, and logging practices you probably have not verified, and the industry includes operators who have logged users while advertising that they do not. Several free VPNs have been caught selling data outright. Where a VPN genuinely earns its cost: circumventing censorship or network restrictions, accessing region-locked content, working on a network you actively distrust, and shielding browsing from an internet provider that monetizes it. If your goal is privacy from advertisers rather than from your network, browser configuration and tracker blocking do far more than a VPN, and cost nothing.
