Most of your monthly active users don't want to read your articles. They want to get their questions answered with as little effort as possible. This is what Google's Overview is doing: it's transforming your articles into a form-factor that the users want. This is what you could be doing as well: rather than creating food for AI, create a mini-AI yourself that answers user questions. It doesn't have to fabricate answers, rather it can quote your memos in a format tailored to users, while your memos will remain private. This will also stonewall Google's AI, for now it would have to interrogate your mini-AI.
