>"For years, the software engineering industry has operated on a comfortable, perhaps lazy, myth: that open source software is an infinite, self-renewing public good that costs nothing to consume and requires nothing to sustain."

Since when? Open source projects have for decades offered paid support. Projects like Red Hat, Snort, Security Onion and others. I don't know anyone that has ever thought this. It's always been generally accepted that someone has to support it, either paid professional services or a full time employee with expertise.
