I mean why invest $70 (and a lot of ressources) in hardware when, in theory, you have everything you need, the software is just locked behind a paywall?
No, they are not. The USB port is (usually) USB 2.0 and the video output, even though the application might claim 1080p 30 FPS, is a 'digital upscale'[1] from XGA or 720p. That in my view is decidedly not 'high quality'. My monitor has eight times that resolution and more than four times the framerate, totalling more than a 32× increase in bandwidth, and it is from 2021.
If users want high-quality video out from their pro cameras, use a capture card or monitor. That's how it's always been. As another commenter said, this article is rage-bait because the OP has purposely chosen a decidedly poorly-supported way to use their camera's functionality instead of the industry standard.

The Canon G5 X II has USB 3.1 over a USB-C port. All of what you said does not in any way shape or form apply to the topic at hand.
This entire comment section is a massive storm in a teacup by photography and AV amateurs who don't know the ins and outs of AV work flows and assume that stuff should just work the way they want it to.
Just because you didn't bother to do any amount of research whatsoever before going on your unhinged rants does not suddenly make them any more relevant when talking about this specific camera. We're not talking about generally ("loss of generality" ok Jan ), we're talking about a specific blog post from a specific person talking about a specific camera.
The fact that you still don't understand this shows you clearly are not responding in any type of good faith here. It's your way or the highway even if your way is wildly outdated and not relevant.
