Tuxedo computers tried and didn't succeed either.
I will never buy Qualcomm again. I avoid them on phones as well by just buying Apple. They do not support their hardware beyond the release.
To each their own, but I don't recall Apple ever mainlining any of their drivers on Linux. You're rightfully angry on the laptop side of things, but Apple is much worse than Qualcomm when it comes to open source support for their phones.
Qualcomm probably shouldn't have promised Linux support in the first place. Everyone seems to love Apple's hardware even though you're practically stuck with macOS. Had Qualcomm just stuck to Windows-only, they would've probably received a much better reception by the tech press.
Not really, the 1st. iteration got stuck in legal land and other delays.
