I didn’t say everyone should necessarily use trilium. I described my rationale pretty plainly. Trilium can be transformed into md files trivially, if it gets abandoned, any users will be fine.

Trilium is literally available as an installer.

Use whatever you want. I’m not really here to describe the entire feature set of trilium for people in a play by play. Go look at the features, give it a try, or don’t, im not about to place massive amounts of personally produced information in software I can’t fully trust though.
