it will be worse when they make the preview readable.
at least at the moment its still pretty useless. people can't really get any info from it. they still have to visit your site.
compare that with the way they do google images. they show the full image and hide your page underneath. the user doesnt really have to visit your page at all now.
if they ever change previews so its akin to the way they do images, then that will be the time to kick up a fuss
ps... aren't the images produced on the fly? that is probably why they can get away with ignoring noarchive, because its not archived.
