Volunteer runs infrastructure for 80% of PHP's code distribution
Source: Six Colors
Rasmus Lerdorf, PHP's creator, has been personally maintaining the package repository that serves the vast majority of PHP installations—a critical chokepoint in web infrastructure that runs on one person's unpaid labor. This exposes a structural fragility in open-source: the more widely adopted a tool becomes, the more its maintenance burden should scale, yet PHP's distribution remains dependent on a single individual's volunteer commitment and personal server resources. Enterprise-scale infrastructure has outsourced its reliability to an arrangement that would be unthinkable for proprietary software.
