Not to toot my own horn, but I'm sure that my post was the one AMD was responding to when they made this statement, because they also commented it in my
post about this issue.
It really feels like they aren't listening because I myself have said many times that the chips in every Ryzen Mobile system - including the PRO chips - are exactly the same and the OEMs don't do anything to the drivers or chip besides limiting the TDP in some cases to keep the system from overheating (which isn't even the case for TDP limited devices). These limits are usually controlled by the BIOS anyways and that's why installing "unsupported" drivers yields in so much success without the device "exploding" or becoming bricked.
The drivers that Acer, Dell, Asus and Co. release on their website are clearly just copy-pastes from what AMD sends them which shows that either AMD is the problem here by not coding drivers, or what I believe is the more realistic case, OEMs have deals with AMD (and maybe other brands) that stop AMD from posting those "reference" drivers to their website and for their own reasons they aren't uploading the drivers they're probably getting from AMD. The OEMs probably aren't updating the drivers on their websites because as you said, it's in their interest if your device doesn't work and you go out, running to buy a new one.
The thing is that in the end, most of us are more pissed off about the driver situation because the devices are so unstable. From random freezing to BSODs, everything can happen which in my case often resulted in data loss - during a class/exam - and is my main reason for trying to get HP to let me switch out my device for a new one. I wouldn't mind some performance issues if at least my device were stable - but that isn't the case and it's the reason so many people aren't recommending AMD laptops and are even going as far as to creating posts to stop people from making the mistake they made.
Please AMD, if you're reading, we love you as a company, Ryzen and Vega are great products, but situation with Ryzen Mobile currently is uncomprehensible and the company's response isn't any better. We'll only start buying your Mobile products again - and recommending them - when you fix this and formally apologize to the community for making them wait this long and triggering an internet-wide shitstorm that really shouldn't be necessary. Come on, you make intel and nVidia look pro-consumer, yuck.
That's the only plausible reasoning there currently is to this situation: generic drivers are being "blocked" by OEMs through a close that was possibly created in cooperation with intel/nVidia to give AMD the bad name they're getting.
The thing is that even if OEMs did a lot of changing with the drivers, things like config files exist so if the OEMs were worried about generic AMD drivers being installed, they would have to implement a config file like that with AMD in the software that possibly users could even configure and everyone would be happy.
I feel you dude, if I'm not mistaken I have the most expensive Ryzen Mobile device on the market - the top-end HP EliteBook 755 G5 - and it hurts, so much that I'm currently working with HP to get the EliteBook 840/850 G5.
I can imagine this being the case as intel has pulled this kind of bs before, nVidia has never done anything as illegal as this though...
