Eh, I think websites adopt webp for their smaller size than anything else.
And I would argue that beside Facebook, the end user right clicking and saving the image for them to use in an inappropriate manner ( downloading the image is not the issue, using it without permission would cause copyright infringement ) would be an issue for some of the website that are hosting the image.
No argument - my point was simply that very few sites on the web fall into that category.

That’s only true for a subset of sites, only to the extent that this wasn’t covered by fair use, and it came up enough that it was a common objection.
Why I love features like Fastly's Image Optimizer. No extra work on our end but we get the bandwidth savings https://www.fastly.com/products/image-optimization
(We evaluated it for storing a bunch of other stuff but didn't find it worth the compatibility and need to transcode problems)
