I’m cool with Obsidian because everything is just a bunch of Markdown files. If they go off into the deep end then I can just switch to VScodium or some random text editor.
Vendor lockin is the real problem with proprietary software.
Btw, I don’t disagree with the title. Of the WYSIWYG markdown editors I’ve tried, Obsidian easily has the best UX with the single-pane preview and inline editing. That being said, Obsidian is trying to be more than a note-taking app. The wobbly graph, canvases, the nonstandard markdown elements might turn people off. The average *nix-user will also likely prefer a community-driven application instead of closed-source, corporate software, gratis or paid.
The issue is that you made the post in bad faith, to evoke a negative reaction. Some will call it an attempt at trolling, but I think the most appropriate description is “being a dick.”
You are in the wrong audience for that, and I don’t know what thought process led you to expect anything but scorn. It’s like going to a sporting event and sitting with the fans of one team while wearing the other team’s colors.
