Linus "Tech Tips" Sebastian introduced the Framework team to the highest level people at AMD he knew last year after his investment in Framework but as of his update video a couple of months ago, nothing really went anywhere.

I highly doubt it's a fanboying issue, they're a small company with big challenges and supporting multiple platforms is not easy at any scale. They also wouldn't want to say anything positive or negative that could sour relations with AMD or other partners in future.
