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.
For keeping profits local? Neither of them.
And to be honest, profits don’t matter. You should care about keeping costs local because profits just got to rich people, while the costs of a product are paid to the poor people who actually make said product. For example, if you’re Canadian, this is why you should buy a Toyota RAV-4 (made in Ontario) instead of a Ford Escape (made in Hermosillo, Mexico) despite Dearborn being closer, because it’s the costs that make the difference, not the profits.
As for eReaders, the question is: do you read comics? If you do, get an iPad. Otherwise, Kobos are fine.
