I liked (and used) logseq for a while (since I could easily relate to the idea of outliner). But their development stalled; now they have moved to db based structure. I am less concerned about open source than open standard. I have had my notes in text, jpg for more than a decade. Have used plain text editors (textmate?), nvALT etc and now use obsidian. I am sure these text files can stay for another 10 years even if obsidian itself goes out of business.
