Overview of VPNs clarifying capabilities and limits: explains how VPNs work, legitimate use cases (remote work, site-to-site, geo-content access), and why they do not guarantee anonymity or security in an HTTPS-by-default ecosystem. Warns about risks of free or opaque VPN providers, potential logging and surveillance, and urges scrutiny of privacy policies and independent audits; notes protocol choices with a preference for WireGuard over weaker setups like L2TP with PSK; and recommends using VPNs selectively for specific needs rather than as a blanket privacy solution.
