The modern world is built on open-source software. It powers critical functionality in our digital and physical infrastructure. Linux is the operating system of choice for a variety of professional applications ranging from web servers to microprocessors. The internet is built on top of open-source tools such as BIND9, OpenSSL, iptables, nginx, and much, much more. It’s what makes it so easy and inexpensive for anyone to set up a website nowadays—imagine if your options were between writing your own networking stack for scratch or paying some company $500 for a “basic” license1.
