Your response is condescending, arguing from ignorance, and arguing in bad faith. I will reply this time, because once again you’re trying to build an argument on extremely shaky ground and I don’t enjoy people spreading ignorance unchallenged. However I won’t engage any further and feed whatever you think you’re getting from this.
I haven’t suggested that people should use Obsidian over OSS solutions. I was simply pointing out your argument against Obsidian’s architecture was poorly founded.
The data you’re insinuating will be lost is pure FUD. While the format isn’t standard markdown, none of the well implemented solutions are, because as you so rightly pointed out, markdown has little to no support for most of these features.
However, obsidian’s format is well documented and well understood. There are dozens of FOSS plugins and tools for converting or directly importing obsidian data to nearly every other solution. Due to obsidian’s popularity, it’s interoperability this way is often far superior to FOSS solutions’.
