I want to buy open source drm free e-books however I see Kobo that is a Canadian subsidiary owned by a Japanese Company while Apple is American with some operations based in Canada, California is closer to British Columbia however they often use closed standards.
Walk into an independent bookstore near you and buy books. That’s how you keep your money local.
I like your thinking, also I should consider donating the books to friends, charities and mini libraries after I finish with them.
