I thought the article was a bit of a needless rant and not very well thought through.
—Most You Tube digital camera reviews seem to be now skewed to highlight the video features and still photographic features get a lesser mention.
YouTuber's are video creators (Hence the video you are watching.....) so have a bias towards video features and specs. That being said I can think of plenty that talk at length about the photographic merits of a camera and put their focus here
—Reviewers tell their audiences that a camera is subpar because it doesn't have features such as external microphone and/or headphone jacks.
Same as the above, your "Reviewer" is a video creator...
—The big headlines lately in digital photography is not about more dynamic range, less noise at higher ISOs, but all about overheating when trying to record video
Completely disagree. This is a recent trend purely revolving around the Canon R5 overheating.....
—A small number, I would bet, yet, we are forced to deal with a swing out LCD that is almost impossible to use with an L-bracket on a tripod. Fujifilm created the absolute perfect 3-way tilting LCD screen then went ahead and ruined the X-T4 by putting a fully articulating LCD screen on it. A sad day for us still photographers.
I've used full articulating screens on an L-Bracket just fine.....
—If you examine almost all firmware updates in the past few years, most seem to be aimed toward improving video. Not much has been aimed at still photography.
Up until recently, Fuji was the only major camera brand doing constant firmware updates because of its Kaizen principle, so not true. And if you look at Fuji's main updates, They have centred around improving auto-focus speed and accuracy which is great for wildlife and sports photography.
—You can no longer buy a digital camera without video, as far as I can find.
Not sure why this is a problem, if you don't want video, don't use it. Even my D3400 had video features and it cost £300.....
—Already 4K video is now passé. 8K vdeo is all of a sudden the "new, best thing" and, mark my words, you will see more and more cameras come out with 8K video in the next couple of years, with a commensurate higher price tag, despite the fact that there is almost no 4k content available for general viewing. I hear the video people now complain about how processor intensive and how much memory 4K takes. Good luck with 8K!
Not sure where the higher price tags comes in, the Canon R5 is on par with the Canon 5D Mark IV when it came out....
—Beyond IBIS, manufacturers are now adding a digital-based IS system so you can walk make your video appear as though it is on a gimbal or tripod. I love the idea of more IBIS capabilities but that digital stabilization feature is not available to still photographers. Yet, another video based feature we still photographers can't use... But we're paying for it.
I don't think the writer knows how digital stabilisation works....
—Today's lenses are being developed and marketed to the video crowd as they can be silently focused. Still photographers don't need silent focusing.
Tell that to a wedding photographer....
