Open Source, Open Mind: The Cost of Free Software

Free lunch, free speech, free time, free spirit... when we talk about something being "free", that's normally a good thing. But as anybody who's ever given away their software for free will know, it's not that simple - and sometimes, it's not clear what "free software" even means.

Work skills

At one end of the scale, volunteers use free software to resurrect old laptops, turning e-waste into useful tools they can donate to worthy causes. At the other end of the scale, tech giants use free software packages to create products which generate millions of dollars in profits every year - but when the creators of those packages try to recoup even a tiny part of that revenue, social media goes into an angry meltdown.

Join Dylan Beattie for a look at the past, present, and future of free software. We'll talk about the history of the free software movement, from MIT's Artificial Intelligence lab, to the shareware and public domain movement of the 1980s, to the era of GitHub and package managers. We'll explore why people choose to give their code away for free in the first place - and what happens if they change their mind. We'll talk about licences and legalities, we'll learn about some of the weird and wonderful edge cases that free software has created over the years, and we'll ask the question: is a truly sustainable open source ecosystem possible, and if so - what might it look like?
