Sponsoring Open Source Maintainers Works - Here’s Proof

Open source isn’t truly “free”, it’s only free to use. The real cost lies in maintenance, which depends almost entirely on volunteers donating their time, expertise, and energy. DNN is a perfect example: despite being old enough to share a timeline with MapQuest printouts and MySpace profiles, it’s still alive because dedicated contributors keep it alive. Yet many modules were created by developers who have long since moved on, leaving behind essential but aging pieces that block upgrades and require significant, often tedious modernization work.

That’s why sponsorships matter. And it works!
