A convincing presentation, I must admit. But Obsidian not being FOSS is a non-starter for me. I find note taking to be an enticing topic and try to follow the space. There is a lot of innovation going on. However, I rarely try new note taking apps. Notion, Joplin, Logseq, Zettlr, Obsidian, etc. Some are better than others for some people/tasks. But at the end, what matters is not the app/platform as much as the actual activity of note taking.
