It was more that Sony, who had thought they bet Blu-ray on the success of the PS3, realized they'd also bet the PS3 on the success of Blu-ray, and spent about $1B paying studios to adopt Blu-ray and drop HD-DVD.

Or how Hollywood studios cut out MacOS X from Blu-Ray and HD-DVD support because MacOS X didn't provide the DRM infrastructure Hollywood studios demanded for Blu-Ray and HD-DVD?
Given that better content security than DVD was a core motivation for new disc formats, it was utterly expected that they weren't going to support a "just buy a Mac!" sized hole for pirates to drive through.

Expected by Apple as well, who knew what they needed to do to support HW encryption, and got it as part of their Intel transition.

It doesn't matter what happened in the distant past, today pre-recorded content is king and DRM is legally empowered by the DMCA. Hollywood studios can cut out from their encrypted content whatever OS and hardware combination doesn't comply with their arbitrary demands.
Studios could only invalidate DRM keys for content on their own wholly-owned streaming services, and I am not aware of them ever doing so. Content distributed by other streaming services control their own DRM keys.

And their demands for secure video paths and HW license stores are hardly "arbitrary" - they have been well documented and understood for years.

The weird thing in this case is that HDMI 2.1 is required only if you want 4K@120fps, and Hollywood doesn't serve any 4K@120fps content, but they can still mandate all kinds of DRM requirements by acting as gatekeepers to the HDMI spec. DisplayPort is technically a thing but isn't a thing on TVs (due to lack of eARC support), so you want at least one HDMI 2.1 port if you want to output 4K@120fps to a TV (which means GPU vendors can't boycott HDMI 2.1). And then there is the open question of whether encrypted 8K content will be allowed on DisplayPort or be HDMI 2.1-only.
I'm missing your point here. Pretty much the only things that can play out HDMI 2.1 so far are recent GPUs and game consoles. Most streaming media players and all disc players are still on HDMI 2.0, and some other than that.

Also, you can do DisplayPort to HDMI 2.1 with an adaptor. Nvidia's professional A-series GPUs have 4 DP and no HDMI ports, so I've used an external adaptor to get 120 fps, which has worked well.

The lack of eARC isn't why TVs don't have DisplayPort input. It's more than TV SoCs don't have support for it, so it would be quite expensive to add it.
