Can I simply say what a relief to uncover an individual who genuinely understands what they're talking about on the internet. You definitely understand how to bring a problem to light and make it important. More and more people really need to read this and understand this side of the story. I was surprised you aren't more popular since you certainly have the gift.
Currently it seems like Wordpress is the preferred blogging platform available right now. (from what I've read) Is that what you're using on your blog?
INAV and Betaflight are different. Use INAV when you need navigation, a plane, a VTOL or a rover. I only download the flight-controller firmware, the Configurator and the 9.1 docs from inavflight.net. Old forum copies are not worth it.
