> and perhaps not coincidentally all of the Plus laptops require reversing

You're still acting as though Qualcomm has made meaningful contributions to Linux support for Snapdragon X Elite in a way that has not also helped Snapdragon X Plus support. But you haven't specifically pointed to any Qualcomm contributions of any nature, let alone ones that were as narrow as you claim. All you've done is point to weak evidence that machines with Snapdragon X Elite bins reached a reasonable threshold of "supported" earlier than models with lesser parts, while ignoring that your evidence also points to the lower-tier processors coming to market later.

Can you point to any laptop device tree that was contributed by Qualcomm, and not merely reverse-engineered from the device tree for the reference design that was not offered for sale to consumers? Can you point to any driver contributed by Qualcomm that works for Snapdragon X Elite SoCs but requires further modification to work for Snapdragon X Plus SoCs?

You made a claim about a pattern in Qualcomm's public behavior, and have identified zero instances of that pattern.
