Last I checked, DisplayPort has an auxiliary communications channel that's at least as capable as HDMI's.

As you mention, the HDMI Consortium prohibits TV manufacturers from using DisplayPort. Many of the things that CEC and friends does aren't really needed in PC land. And if the Consortium is going to prohibit TV land from using DisplayPort, why go to the trouble to implement and standardize the parts of CEC & etc. that are only really useful for TVs, home entertainment centers, and the like?

IANAL, but this seems anti-trust-ish.

US antitrust/consumer-protection people have been asleep at the wheel for decades now. I'm doing my (tiny, tiny) part by avoiding HDMI wherever it's at all reasonably possible and recommending to folks I know that they consider doing the same.

“Only” is doing a lot of heavy lifting here. The pc market is a tiny minority of customers. Most of the real volume is sadly just a soundbar plus a tv plus some device like Apple TV. The majority of the market by dollar is ultra high end setups which absolutely depend on hdmi. Not for cec which fails miserably with more than one device in the chain but because the AV devices only support hdmi. I wish they had DP but the anti consumer licensing does not allow it.

Is it? Let's read on.

You're aware of the fact that HDMI licensing seems to prohibit the installation of DisplayPort ports on TVs. Good. That's what I said, upthread:

> [T]he HDMI Consortium prohibits TV manufacturers from using DisplayPort. Many of the things that CEC and friends does aren't really needed in PC land.

So. Given that review of the previously-presented information:

Why would the DisplayPort folks (and/or manufacturers of equipment using DisplayPort) go to the trouble to standardize device control protocols that are only really useful in TVs and the like? As I said, that doesn't make any sense for a port that doesn't get used on TVs and associated TV support hardware... does it?
