HDMI Forum is unwilling to disclose the 2.1 specification for open-source (Linux): according to AMD, they had submitted a functional, HDMI 2.1-compatible driver [for linux?], which the Forum rejected. (www.heise.de)

I do not really have a body for this. I was not aware that this is a thing and still feel like this is bs, but maybe there is an actual explanation for HDMI Forum's decision that I am missing.

The renaming while still selling it with older packaging for years has been angering me since it happend.

Honestly it would not be so much of a problem if things where actually labeled appropriately with all the actual specs and support features on the package but its more profitable to keep you guessing (and going for the higher priced one just in case)

They do the same thing with Bluetooth audio transmission usb, their “high quality audio” and “ps5 compatible” but does not tell me wether it supports aptx or not?

Also the whole “buy a product clearly pictured with usb A type connector, receive a USB C type connector variant, if lucky, with an added adapter.

Yeah, "3.0" and "3.2 Gen 1" mean the same thing. Same with "3.1" and "3.2 Gen 2x1". I've bought computer cases in 2025 with the front IO labeled "3.0".

How are normal people supposed to keep track of this?

Imagine how big the connector shroud would have to be to show all the features in a cable!

Incidentally the last power cable I bought to replace my failing MacBook power cable is labeled for max wattage.

Isn't aptx only supported on quallcomm chips?

I have done research into what product i should buy three times and i am still not sure enough to answer this. That says enough about how confusing the modern tech market is.

They are definitly proprietary and a competitor to LDAC from sony. Finding something that supports both sennheiser and sony headsets without being overpriced is a nightmare.
