This isn't about Kobo using Rakuten, this is about Rakuten buying a tool to get into ebooks outside japan. They already tried with the Sony-Panasonic alliance but clearly didn't see it helping them outside Japan (assuming it is working even there). Kobo didn't decide; Rakuten did.
The Indigo folks would know why they made the move but I'm thinking they realized Kobo is a long-term, deep-pockets bet. And not a sure thing.
A bird in the hand and all that.
Kobo is just a tool that got a new owner but likely keeps its mission.
Could've been worse.
