Except an artist can deliberately decide to only make an image publicly available for a limited time, and therefore taken the image down from the website. Just like art moves from museum to museum, an artist can allow an image to be used within a pre-defined window. Just because you have the technical know how to extract an image that is not readibly downloadable via the UI does not mean you should.
Maybe one of the features of JXL would be a timebomb type of setting where after a certain date the data is no longer useable.
I sympathize with both sides of this argument. I get that info wants to be free blah blah, but I also understand that artists are in a difficult situation with the internet. I mean, an artist's work posted on the internet is not the cure for cancer, or basic information on algebra where the info should be evergreen. The group think is more of "I want what I want" vs consideration for what the artist's intentions are. If you enjoy an image so much that you're willing to go to the effort to get the image, why not acquire the image throuh legit method?
