full control over notes isn't something I would consider a priority personally. They're flat note files. Taking the effort to migrate them isn't really enough of a deal breaker for me to futz about with hosting my own platform and "all associated dev ops". Knowing where my note files are and not having to worry about accessing them is a priority. Whatever metrics you want to point at as to how long Google service x survives doesn't magically make that clock go away in my mind. It's there. It's present.
