Early evidence is that they are listening and responding. https://mega.co.nz/#blog_3
Let's see what the response is to this piece.
I for one am not going to judge them too harshly if they keep listening and responding, as the product will just keep getting better. Sure they are blessed with I guess several million customers a few days after launch, but many here have also been through early product issues, albeit with far fewer customers. Like Mega, we learn and move on by fixing the problems.
I guess Mega appreciate the value of this sort of feedback, and the attendant publicity.
Edit: and just after publishing this, a tweet from Dotcom: "We welcome the ongoing #Mega security debate & will offer a cash prize encryption challenge soon. Let's see what you got ;-)"
