What's with the snarky comments? The guy build a successful business with happy customers. He didn't make it in 2% of his time, he built it over the years with experience from other projects and solved an issue people are willing to pay money for. Maintenance now might be on low time but doesn't mean it's easy to solve a problem and consistently ship the solution. I honestly think most of you have a misunderstanding about serviced software and the demand for it. The fact that you can do it with a Docker script and some time doesn't mean it works properly for all use cases or everyone can and should manage that infrastructure themselves. Some people happily pay for it so they don't have to worry whether their instance is still running and can call support instead of firing a terminal and looking through obscure Stackoverflow answers. He even open sourced his entire business. Instead of throwing apples, try to learn something or at least appreciate the effort.
