You claimed it wasn't clear how Qualcomm could help. I pointed out how they could help. There's precedent too, with ARM supporting panfrost.
QC is not a low level employee lacking agency over their job description. They're a business that is free to set their strategy in response to risk and competition.
The less that QC upstreams, the more risk they incur, especially with tightening security scrutiny (e.g. 2021 Cyber EO requirements).
QC can also get disrupted by Mediatek doing a better job with Linux.
