Corporate Source vs. Open Source

Short Form


Has Open Source sold out? Has the corporate world somehow managed to take over the soul of open source without anyone noticing? When did open source "projects" requiring hundreds of thousands of dollars to participate become a thing?! In this talk we'll explore this and what it means for the OSS community at large.


Do you know the different interpretations of “free”? If you’re in open source, you should. In this talk we’ll take a walk down memory lane in roughly the past 20 years of open source, how what “open source” means has changed and evolved, and how companies have in some senses co-opted it rather brilliantly to what I would say is our detriment. Gain some insight into the history of our beloved industry through the thoughts of those who were there to create it, the philosophical ideas that powered it, and how those ideas have both evolved and been in some ways subtlety manipulated in the years since.
