The difference is the timeline. Basic support landing ~1 month before launch is not acceptable. We barely have a stable kernel with this initial support, and that kernel won't have been picked up by any distributions. Further, for previous AMD hardware releases, this initial support has not been really usable from what I have read. Most of the posts I found on Reddit pointed to it taking several months after launch for the Navi drivers to stabilize. Even then, running a custom kernel in my experience is a lot more trouble than the proprietary Nvidia drivers. Compare to Intel where you have initial basic support landing around 2 years before launch with incremental improvements following. This is the correct way to do open source drivers.
