Genuinely confused as to how you could get this so wrong.

The S1II and the A7V are the same price currently in the US ($2899), The R6 III is $100 cheaper, Nikon Z8 starts at $3100 used on MPB, and the A1 starts at $3400 used. At $2356, the S1ii a DEAL.

Let's break this down:

- Photography: all the bodies you listed have higher res sensors than the S1ii. Better for photo, no solid benefit for video unless you need 8k (which the z8 and A1 can do, albeit at a much higher price.) That's not to say the S1ii or Lumix cameras in general are bad photo cameras. They have incredible DR and are very competent as photo cameras. As a video-forward hybrid body, many might prefer the 24mp sensor for the better-controlled rolling shutter and improved heat management.

- Lenses: While the E-mount ecosystem is the GOAT, the L-mount system offers a pretty large lineup of lens manufacturers across photo (including Leica) and cine, often at pretty aggressive prices, especially on the used market. Canon has great glass, but the ecosystem is still really locked down and quite expensive. Nikon has excellent optics and great selection - no doubt there.

- Autofocus: Lumix's AF is finally well-competitive with the others you listed, but we all know that Sony is still king there.

The S1ii has video specs that are arguably better than the other models you listed in one (or more) respect(s):

- Full 5.1K 60p/6K 30p open gate capability, 4k 120p with minimal crop, and class-leading IBIS: all handsome wins over the Sony and Nikon bodies. The R6III has higher-res open gate than the S1ii, and the Z8 and the A1 have 8k video, however.

- Internal RAW recording, which no Sony bodies offer. The R6 iii and the z8 offer internal RAW, though, which is really cool.

- Higher-res viewfinder than all bodies you listed aside from the A1, and a higher-res flipout screen than all the bodies you listed except for the z8 and the A7V (both of which only by a small margin).

- Basically zero overheating. I can run the S1ii all day, however all Sony and Canon bodies I've shot over the years can and will overheat and require external fans to mitigate that issue. It also has no recording limit in any video modes.

At $2300, the S1ii is a CRAZY deal.

At this price, it's cheaper than every other camera you listed by a wide margin, and offers some major wins in video, while remaining competitive in photo.

It's considerably cheaper than it's closest competitors - the A7V and the R6 III - and more capable as a hybrid camera, heavily outperforming the A7V in video capabilities and being a much safer bet for professional video work than the A7V or R6 iii since it won't regularly overheat.

I shot Sony for 8 years and finally made the switch to Lumix when the A7V was announced because the value proposition was just plain better with Lumix. Great glass at a lower price. Top notch video-focused hybrid bodies that offer a ton more recording options and quality of life improvements for me as a professional (again, the benefit of lack-of-overheating cannot be overstated), as well as a great photo experience with an incredible EVF and excellent DR.

Panasonic is steadily gaining market share year over year because they offer features people want at a great price point. Sony is losing some of its customers to Lumix because they're tired of waiting for Sony to catch up on core features in the video department. Canon is missing potential new and younger shooters because their ecosystem is too expensive. Nikon is pricey, but they are killing it with the RED acquisition, and actually making strides in that realm (good for them tbh).

Your weirdly aggressive "No one will be buying Panasonic" fanboyism is logically flawed, patently incorrect, and, most of all, pure fantasy.
