The same applies to Pixel devices and Apple devices. There might be exceptions I'm not aware of but it's definitely not the industry standard for USB-PD charging cables to come with 3.0 or faster data transfer speeds as the extra wires increase cost and decrease flexibility, which makes them less suitable for a daily charging cable.

Same for the Pixel 6A. Google charging cables are all 2.0.

Edit: The above sentence is incorrect, I misread a source. The original Pixel shipped with a USB-A to USB-C cable that supported 3.0 speeds and a USB-C to USB-C cable that supported 2.0 speeds. Since the Pixel 2 they only ship with USB-C to USB-C cables that support 2.0 speeds.
One could speculate that the moment Google knew their phone was a success, they stopped caring about open standards.
