Open source is all about sharing, keeping code open and providing universal access. That, at least, is the received wisdom that has helped guide open source programmers and companies for the last two decades. But a look at the history of open source projects such as Linux suggests that sharing and openness were not actually the primary motives of their founders. Here's why.N.B.: This is the first in what will, will any luck, turn into a series of posts about the history of free and open source software, which I am researching for (what will hopefully become) a book. I thank my ever-generous editor here at The VAR Guy for, first, allowing me to take a break from coverage of day-to-day open source news items to work on this book and, second, letting me use this site as a platform for exploring some of the ideas that are emerging from my ongoing research.
