To be fair, and note that I think of the hdmi foundation as the bad guys.
hdmi was not an alternative to display port, display port did not exist yet. it was an alternative to dvi, really hdmi is dvi with a sound channel and drm. And as much as I dislike the hdmi foundation I can see the benefit here.
as to hdmi vs display port... I have no idea why you don't see more display port, VESA has a proven track record as the nicer standards body, display port is a better system. probably just inertia at this point.
As a media tech guy (running the media tech department of a university, which includes a DCI conform cinema): absolutely everybody hates HDMI. It is unreliable as hell, both physically and as a protocol. It tries to be too much to too many people and most devices, including expensive "pro" gear includes unchangeable random weirdness like ignoring EDIDs or forcing them onto you, that is documented nowhere and you can only find these things out when you buy it.
Add to that the fact that consumers/users can break the picture/sound in 100 different ways on their devices and you get a veritable support nightmare.
Isn't this why VGA is still widely used everywhere? It always just works no matter what even when connector or pins are damaged since there's no digital handshake or error correction just a basic analog pipeline.
I don't know, at least here (Europe) VGA has pretty much died out in all but legacy applications. The true pro format would be SDI using BNC connectors.
But I guess HDMI is going to be replaced by USB-C in the long run. Especially since the "everything-connector" also doing Video makes more sense than the video-connector also doing everything.

Sadly this is not entirely a HDMI-specific problem either, he has a displayport feeder too. Also DisplayPort had many problems with disconnects/sleep state for many years, especially surrounding EUP Compliance/EUP Deep Sleep mode. I wouldn't say DisplayPort monitors were relatively bulletproof until the GSync Compatible generation finally rolled around in 2019-2020.
I used a plasma panel, vintage 2004 (retired in 2016 with no noticeable burnin), that had a DVI connector with HDCP support. If it had not supported HDCP, I could not have connected my cable box to this panel.
