In this part of the series, John Graham-Cumming discusses how Cloudflare thinks about open source software and patents. He explains that while they don't believe any single line of code provides them with a long-term advantage, they do open source some generic pieces of software when it makes sense for others to use them. The company also holds patents defensively to prevent others from using the patent system against them. Additionally, Cloudflare engages with governments early on to help shape policies that affect their business and encourages people to engage in the political process rather than demanding corporations act as gatekeepers.
