This statement is a complete nonsence. All USB-C cables I received with Windows laptops and android devices allow very fast transfer speed, way higher than 500 MB/s.
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.

One could speculate that the moment Google knew their phone was a success, they stopped caring about open standards.
