I think they could possibly accept bitcoin as a method of payment in the future, however at launch mega will be free for customers.
http://mega.co.nz/#/investorsWe have raised sufficient funds to cover the launch, but we would like to provide Mega free of charge for as long as possible. If you would like to be part of the success story, please get in touch.
glassuser - Maybe if bitcoin was the only payment option, but that would be incredibly stupid considering you lose access to say 98%(and that figure is low) of your old customer base not being able to pay with cc etc who have not even heard of bitcoin.
You're right about that, at least those who want to remain anonymous would def consider bitcoin over fiat.
