Imho, because of its complexity to setup (compared to other alternatives), Dendron is not suitable for normal or non-geek users. But it also depends on what you want to do with Dendron. As for me, I come to Dendron just because I want something to easily publish a personal wiki on my own custom domain. With Obsidian or Logseq, you can also achieve that but it's not simpler/cheaper than Dendron
