Re:USB4 v2 is also 120 Gbps by cogman10 on Friday September 02, 2022 @05:22PM (#32695860)
The reason is $$$

Unfortunately, USB has more features than USB manufactures want to support. So, the end result is a bunch of those features are optional. That complicates everything. Is this a USB-C cable that can support PD 3.1? Who knows! Because, not all USB-C cables NEED to support PD 3.1, some of them just need to transmit data at USB 2.0 speeds. Those can be made super cheap.

This is especially bad when talking about things like devices. Sure, every device now-a-days has the USB-C connector, but does your phone really need to be capable of doing 80gbps on that port? Nope, so it's optional. (and would be sold, rightly so, as a power saving measure).

Every USB feature has a fast, cheap, low power tradeoff going on and the standard allows for you to mix and match features to your heart's content.

It's not necessarily about 'wanting'. Manufacturers have to hit certain price points, otherwise they lose business to the competition that does.

Yes, it's about dollars. But mostly consumers' dollars.

Assuming you just mean the higher power levels, I'd say that's one of the most minimal issues. Every cable supports at least 60 watts, and you rarely need to consider it.
