Beware: the Sonic the Hedgehog comics from the Humble Bundle bundle appear to be DRM-tied

This bundle: https://www.humblebundle.com/books/sonic-35th-anniversary-megabundle-idw-books

These #SonicTheHedgehog #ebooks are activated on Neon Ichiban, and they appear to have #DRM because, on the titles' pages, each has the "❌ Downloadable" tag under the title, like in the screenshot attached as an example, and have no other indication of technologies included or otherwise.
