> It is very likely that most Qualcomm customers like Starlink have access to the source code of the Qualcomm proprietary Wifi driver for the QCA wifi Access point SoCs No. They are jus that hard to work with. MTK, Qcom, BCom are all terrible with software support, no matter who you are.

Unless you're Apple, I'd make an exception there - they absolutely require support from their vendors for all their non-standard stuff: AirPlay WiFi-based screen mirroring, Handoff, Thunderbolt-based Target Display Mode / Target Disk Mode. Apple always demands to be in control of what is running on their devices, no matter what - even where it's pure software that's concerned, like with the NVidia fallout - and they (usually) insist on quality... there's a reason why Apple hardware feels so painless to interoperate, compared to the Windows or Linux world.

  I doubt Apple ever had real access to something like Intel ME though.

Candela Technologies for example has access to the QCA wifi firmware source code for the QCA Wifi 5 AP chips. They provide custom builds here: https://www.candelatech.com/ath10k.php https://www.candelatech.com/ath10k.php I know of one other company. I do not know if they also have access to the driver source code, but I assume so. Silicon vendors often do not care about small customers, small is probably less than 250k units per year. If you are a customer which is expected to generate more than 5% of the revenue for the complete product line or the business unit then you get good support from these companies. The proprietary Broadcom Wifi driver was leaked multiple times by some companies which did not run the script to clean a GPL tar, but did something on their own and forgot to remove the Boardcom wifi driver source code. Last time I saw this was already 8 years ago. The Broadcom proprietary Wifi driver also contained the source code of the firmware running on the ARM chip inside the Wifi IP, at least it did this some time ago. For the Qualcomm 5G modem and the graphics driver this is probably different.
