I think you are doing the post injustice by hijacking it. FOSS maintainers can get a burnout even without toxic users - hard deadlines and the understanding that people really rely on your project can do that to you.
e.g.: About 25 years I had developed some blogging software in the style of usemod (single executable, data stored in ./data) for coordination of and reporting about protests on throwaway VMs. This initially was a weekend project but spiraled out of control when it made its way through Europe and people called me for setups or features for other actions. My burnout was the result of trying to help grass root organizations while also being politically active myself and having a full time job. The solution was basically what the article says:
* invited more maintainers by dumbing down the implementation so that one does not need a black belt in perl to hack on it
* created minimal docs
* I found hoster in the scene who was competent and willing to do pro bono hosting in exchange for me being available in case of problems (he never called me).
