USB can do just about anything. Video out is one possibility. But HDMI can already do that.
It doesn't make sense to expect the manufacturer to provide a free app to make USB do something you can already do over HDMI, and for which HDMI is intended.
This article is rage bait where there's no real cause for outrage. But it's adjacent enough to "right to repair" and "subscription fatigue" that it sounds outrageous.
The video feed should (depending on usecase, sure) be compressed on the device and sent over USB.
Sending uncompressed video just to be badly compressed in a capture device is most definitely not the right tool for the job.
These cameras are not made to be webcams. OP is using theirs as one, and that's fine; I do too. But device-side compression for USB video out, a webcam app, etc. are webcam features. They come at a cost, and many camera buyers don't need them.
For those of us using these cameras in these nonstandard ways, we can reach for HDMI, which is the right tool for this particular job.
The standalone cameras I've used haven't included free webcam functionality and I don't think that's outrageous, but apparently many people here who've been downvoting me disagree.
Personally, I think HDMI is great for A/V tasks that a camera doesn't support out of the box since it's a widely supported standard.
Your HDMI capture device (which is a cheap portable device with limited processing power) is probably going to do a much worse job.
Sending uncompressed video over usb is absurd.
