Honestly, if this is true, whatever.

The worst part of USB C is that the quality of the cable is a complete unknown to people at a glance, the only way I can tell my Thunderbolt 4 cable from any other USB C cable is that the TB4 cable has a larger boot around the connector.

But even that isn’t a guarantee to it’s quality, data rate, or power transmission.

If mfi means that it meets a minimum spec, fine by me.

If not though, then Apple can pound sand.

I imagine MFi certification will mean it meets some specification. Apple wants everything to just work and the absolute mess of USB-C goes against that. I'm very much ok with this and actually wish there was some more regulation/transparency with USB-C. Too much confusion for people that aren't already geared towards looking at the details.

Actually, the Thunderbolt 4 trademark on a cable IS a guarantee of quality, data rate, and power transmission! Intel tests and certifies the cable meets design requirements, and then they audit these cables in the field to make sure they continue to do so through the production run. As far as Speed goes: all TB4 cables are 40 Gbps. For power, all TB4 cables are 100W (5A) capable.

Note: at some point soon, all TB4 cables will be 240 W capable, I just don’t know when this will occur… it is a newer Type-C spec.

Your thunderbolt cable doesn’t have the thunderbolt logo? Both of mine do.
