    The Messaging App With No User IDs (SimpleX Interview)

    SimpleX Chat is the only messaging network where users have no identifiers—no phone numbers, no usernames, no user IDs at all. Henry interviewed founder Evgeny Poberezkin about how unidirectional message pipes create a network where servers don't even know users exist, why this isn't federation, how it compares to Signal and Session, and why the company is based in the UK despite encryption battles. 🔗 SOURCES & LINKS • SimpleX: https://simplex.chat • Evgeny's Website: https://www.poberezkin.com/about.html ⏱️ TIMESTAMPS 00:00:00 INTRO 00:01:31 SIMPLEX NAME 00:04:20 SIMPLEX TEAM 00:05:10 SIMPLEX VS.

    It's Time for the VPN Industry to Innovate (Obscura Interview)

    You don't have to trust Obscura—you just have to trust that not both Obscura and Mullvad are compromised. Henry sat down with Carl, former Bitcoin Core developer and founder of Obscura VPN, to discuss how it's the first VPN that mathematically can't log your activity, what makes it censorship-resistant against networks like the Great Firewall, and what it really means to build privacy that's more than "a pinky promise." 🔗 SOURCES & LINKS • Obscura: https://obscura.net • GitHub: https://github.com/Sovereign-Engineering/obscuravpn-client • Trust, 2-Party Relays, and QUIC: https://obscura.net/blog/bootstrapping-trust/ • Mullvad: https://mullvad.net ⏱️ TIMESTAMPS 00:00:00 INTRO 00:01:50 CARL'S BACKGROUND 00:10:47 APPLE'S PRIVATE RELAY 00:17:11 TRUSTLESS MODELS 00:19:05 MULTI-PARTY RELAY PARTNERSHIP 00:21:39 TRADITIONAL MULTI-HOP 00:23:39 CENSORSHIP RESISTANCE 00:27:33 MULLVAD VS.

    Why F-Droid Still Can't Get on iPhone (FSFE Lawyer Interview)

    The Digital Markets Act is a can opener for Big Tech's walled gardens, forcing Apple, Google, and Microsoft to open their platforms whether they like it or not. Henry sat down with Lucas Lasota from the FSFE (Free Software Foundation of Europe) to understand what the DMA actually does, why Big Tech is fighting it in court, and what it means for open source software and your digital freedom. 📱 RESOURCES • Free Software Foundation Europe (FSFE): https://fsfe.org • Free Software Foundation (FSF US): https://www.fsf.org • Public Money, Public Code campaign: https://publiccode.eu ⏱️ TIMESTAMPS 0:00:00 INTRO 00:01:36 WHAT IS THE FSFE? 00:04:12 LUCAS' ROLE AT FSFE 00:05:44 INTRO TO THE DMA 00:09:45 THOUGHTS ON REGULATION 00:12:47 PUBLIC MONEY, PUBLIC CODE 00:21:25 BREAKDOWN OF THE DMA 00:30:54 DMA ENFORCEMENTS 00:31:44 INTEROPERABILITY 00:36:20 DMA ENFORCEMENTS (CONT'D) 00:38:50 DMA CRITICISMS 00:50:41 USB-C ON IPHONES 00:53:03 APPLE'S "MALICIOUS COMPLIANCE" 00:56:57 UNDERSTANDING THE EU 01:02:12 EU COMMISSION & OTHER ORGANIZATIONS 01:06:58 DMA'S GLOBAL INFLUENCE 01:11:57 BIG TECH + INTERPRETATION OF LAW 01:18:23 OUTRO 🎥 VIDEO Watch on YouTube 🧡 SUPPORT TECHLORE Keep Techlore Talks independent & growing: ★ Support this podcast ★
