Why Everyone Should Use an Ad Blocker (AdGuard Interview)

Why It Matters

As tracking techniques grow more sophisticated, a multi‑layered, open‑source privacy suite like AdGuard becomes essential for protecting user data and maintaining trust in digital services.

Key Takeaways

• AdGuard evolved from ad blocker to DNS, VPN, mail services.
• DNS filtering protects whole network, including smart devices.
• VPN masks IP, preventing unique profiling across services.
• Open-source rule sets enable community-driven, cross‑blocker compatibility for adblocking.
• Users must vet ad blockers due to broad permissions and trust risks.

Summary

The Techlore Talk interview with Andre from AdGuard centers on why modern users should adopt an ad‑blocking solution and how the company has expanded beyond simple browser extensions. Starting as a premium ad blocker in 2009, AdGuard now offers DNS‑level filtering, a VPN service, and an email‑relay product, positioning itself as a comprehensive privacy suite for iOS, macOS, Windows, Android, and even smart‑home devices. The discussion also highlights Apple’s new privacy‑focused API, which could reshape how web requests are filtered on Apple platforms.

Key insights include the rationale behind DNS filtering—providing network‑wide control for devices that cannot run native blockers, such as smart TVs and fridges—and its limitations, like the inability to block multi‑purpose domains without breaking services. The VPN layer adds anonymity by sharing IP addresses among users, while the mail relay shields the user’s real email address from trackers. AdGuard’s rule engine runs on open‑source filter lists hosted on GitHub, fostering collaboration across the ad‑blocking ecosystem and ensuring cross‑blocker compatibility.

Andre emphasizes that ad blockers are “very powerful software with broad permissions” and warns against blindly trusting any solution. He cites examples such as Facebook’s dual‑use domains that can break apps if blocked at the DNS level, and the emergence of persistent identifiers like email addresses that require additional protection. The interview also notes Apple’s upcoming API, which will give developers new hooks for privacy‑enhanced request filtering.

For consumers and enterprises, the takeaway is clear: comprehensive privacy now demands layered defenses—local filtering, DNS control, VPN masking, and email obfuscation. Choosing a transparent, open‑source provider like AdGuard mitigates the risk of malicious ad‑blocking software while aligning with evolving platform privacy standards, especially on Apple devices.

Original Description

Ad blockers have broad permissions to intercept all your web traffic—which means you need to know which ones to trust. Henry interviewed the CTO and co-founded of AdGuard about why they pivoted from data collection to privacy protection, how DNS filtering differs from local ad blocking, and Apple's revolutionary new API that lets ad blockers work system-wide on iOS without ever seeing your traffic.
