Agreed, I've been burned too many times by companies getting acquired or deprecating features that I relied on. Open source tools might not be as polished as Roam Research or whatever other fad is going on at the time, but I know they are more likely to stand the test of time. My personal setup is creating markdown files with vimwiki and using fzf for file search. Occasionally I'll use https://obsidian.md https://obsidian.md to visualize my knowledge graph but otherwise I don't depend on it.
