461: AI Security Frontiers, Steam’s 5% Surge, and the GIMP vs. Adobe Showdown  
Podcast: Destination Linux
Published On: Mon Apr 13 2026
Description: In this episode of Destination Linux, we are joined by Red Hat design legend Máirín Duffy (Mo) to tackle some of the biggest shifts in the open-source ecosystem. We start with the massive news that Linux has officially surpassed 5% market share on the Steam Survey, a historic milestone driven by the Steam Deck and the end-of-life for Windows 10. Next, Mo provides an expert breakdown of how AI is revolutionizing security research. From Project Glasswing to the Alpha Omega project, we look at how frontier models are being used to find (and fix) vulnerabilities in critical infrastructure like the Linux kernel. We discuss the "personality quirks" of different AI models and why human expertise is still the "apex predator" in the security chain. Ryan also shares an update on his "GIMP Challenge," revealing how he’s successfully moved his professional thumbnail workflow to open source. This leads to a deep dive into Adobe’s recent "bad behavior," including $150 million settlements and secret modifications to system hosts files. We ask the tough question: When does commercial software become malware? Plus, we cover the latest news, including Linux 7.0-rc7, Firefox’s new free VPN, and Zorin OS’s firm stance against mandatory age verification laws.
