Ironically on Kobo you can buy Enshittification with DRM:

"Download options: EPUB 3 (Adobe DRM)": https://www.kobo.com/gb/en/ebook/enshittification-4

Kobo does sell some other books DRM-free, so perhaps this is some sort of error. You can buy it directly from the publisher without Adobe DRM, there it has a watermark instead.

Depends on the region and publisher. On the Canada site, where it's published by Farrar, Straus and Giroux, it is DRM-free. https://www.kobo.com/ca/en/ebook/enshittification-2

So maybe it's screwup on the UK site.
