It appears that Jim Zemlin, President of the Linux Foundation, was using MacOS while declaring "2017 is officially the year of the Linux desktop!" at the Open Source Summit 2017. This was observed by several YouTube channels Switched to Linux and The Lunduke Show. Finally it was reported by Its FOSS.
With this year’s Linux slogan, It becomes rather ironical that Zemlin would present a slide presentation using Apple’s macOS, which for some reasons he has been spotted by some security developers at Google using twice in last four years.
In March Zemlin told a cloud conference that organizations that "don't harvest the shared innovation" of open source "will fail."
Jim's career spans three of the largest technology trends to rise over the last decade in mobile computing, cloud computing and open source software. He has been with the foundation since its inception in 2007 after a merger between Open Source Development Labs (OSDL) and the Free Standards Group (FSG); the latter being headed by Zemlin at that time
