For Women's Right Day, the android app store featured the lead of Security and Privacy of this very app. A lady BTW. Fuck me sideways how that was a ton of crap, retrospectively. She said in so many words the usual "privacy foremost" and other such obvious shit, then she also said "no selling ever".
I despair of humanity.
ebook.com has a tickbox in its search tool to look only for drm-free books. I miss-clicked once, buying a locked book & was refunded with zero hassle.
Tachyon Publications straight out does not sell drm-locked books.
