Mojang is no longer an indie developer

By entering into an agreement with Microsoft to put Minecraft on XBox 360 exclusively among consoles, Mojang has given up its independence and has chosen to be bound by contracts and PR guidelines that control what Notch is "allowed to say".

PR guidelines are what happens when you sell out.

There's nothing wrong with selling out, it's a stage that many people and organizations pass through. But once you've sold out, the "indie" label no longer applies.
