I wonder if and how Apple verifies these photos were shot with an iPhone instead of other devices with the resolution and metadata manipulated so that the images appear to be shot with an iPhone?

If someone knows what they are doing, it's pretty much impossible to know if the metadata has been changed. It's fairly easy to change the EXIF metadata. 

Simple, they hold their finger down on the image to make sure it is a Live Photo! 

I wish this article came out a few weeks ago! I often Airdrop photos from my iphone to my iMac and I never saw any issues until a few weeks ago when a dozen or so images had this corruption with green rectangles on one side, as well as some discoloration. I could not for the life of me figure out why they were corrupting on my iMac while they looked fine on my iPhone!  Too bad I deleted them...

Is there an option to save in a format with LESS compression instead of even more?

I don't store thousands of photos on my phone and have lots of storage capacity so file size isn't an issue. Image quality is. It would be nice to have a choice of something lossless, or at least only gently compressed. It makes editing so much easier.

If you care about image quality, rest assured that JPEGs are in every way just as good as uncompressed, to the human eye, as long as you save them as high quality jpegs which is how the Apple settings save them. As someone who works as a high end retoucher for 25+ years, I have done numerous testing with JPEGs. You can resave a jpeg in photoshop at level 10 or 11 (not even the highest setting of 12), a dozen times over, and while your image will recompress over itself each time, you won't see any artifacts unless you zoom in at a pixel level which is irrelevant at normal viewing size. When you buy the most expensive high quality stock image from a stock image house, it comes to you as a jpeg. And now we know they are much safer to use than Apple's more efficient HEIC files. If you are going to keep resaving over your image over a dozen times then I would recommend a lossless compression like LZW TIFF or PNG, but most people only edit an image a few times.

All sounds pretty good to me and the stock dropped 4% instantly after closing... As usual!

so beautiful...
