  11. Are you talking about this blog post? https://glaubercosta-11125.medium.com/sqlite-qemu-all-over-a... What part(s) is/are inflammatory? (I'm honestly asking because I don't see anything obvious and I wish to understand your perspective. I'm not trying to imply that there's nothing inflammatory there by using a question)
