While that may be true, so far at least they seem to be doing an OK job. Their ebooks are often sold sans-DRM, and in the cases they aren’t every one I’ve gotten has used Adobe Digital Editions which are easy to strip the DRM from (and is a widely supported standard unlike Amazon’s proprietary DRM scheme). Additionally their e-reader devices, while not open hardware are repairable with disassembly guides provided by them and they even sell replacement components like screens. I have not verified this claim, but they also claim to use recycled plastic for manufacturing them and recycled cardboard for their packaging (should you care about such things).

For better or worse, if you want a Kindle like experience, you’re likely going to be forced into working with a large-ish corporation, but despite the average experience when doing so that doesn’t mean that corporation must be an evil anti-consumer hellscape of rapaciousness and greed. So far at least, Rakuten/Kobo seem to be doing OK by their customers.
