While Gamers Nexus does some decent work, he suffers from what a lot of youtubers suffer: clickbait titles, sponsored segments, unnecessary long videos, etc.
Some find this so annoying, that they downvote this kind of content.
Also that asus scammed gamers nexus is not that relevant for most of us. I am not saying its irrelevant, but there are bigger news.
Saying Obsidian uses just TXT files suggest, that I could use any editor and that Obsidians file format is compatible with any editor. That is technically the truth, but the problem is, that if I decide to use another editor I might get problems because of the lacking ability to usefully edit the metadata. So, if I use Obsidian, the files are de facto not compatible with other editors.
Of course I could switch off of Obsidian and I have the raw data, so I am not locked in. But I think stating that obsidan uses just txt files without any explanation is a bit misleading.
