Here's a question that's hard for me:

Buy an ebook from some tiny publisher in Britain where they email you the book and recommend converting formats with calibre, or buy it from kobo where it has DRM.

As in which company is more likely to leak my personal data?

Also I wonder which would be cheaper to me a US resident, an ebook at 7.99 GBP or 11.99 USD?
