They were likely saying that 8K displays are way out of budget for most consumers.

Where I live, we have 50 inch 8k TVs for 180 USD.

Do many people use Firefox on 50" 8K TVs as opposed to regular monitors? I wouldn't want such a large display on a computer unless the computer is being used as media server. And my experience when I got new monitors for work about 18 months ago, was that decent ones at higher than 1440p were more expensive than I felt was worth it.

Also, I expect one or more of the following from a 50" 8K TV at that price:

- Bundled with ad/spyware.

- Poor image and/or sound quality.

- Doesn’t last long, or image quality very noticeably degrades after a relatively short amount of use.

I also wonder if perhaps it’s still like back when HD was still new, where TVs would advertise “Full HD”, but were actually only referring to being able to accept a 1080p input signal which they would then downscale to their <720p LCD panels.

All of that is probably true, but playing YouTube on such a cheap TV is a very valid use-case for Firefox.
