When they launched the App Store Apple took a risk - invested in the systems etc needed to support it and I think that at the time it would be possible to justify 30% as reasonable given these factors - and was comparable with other stores.
I think it would probably be hard to argue, given the market structure now, that the return relative to risk is still reasonable. Normally other entrants would join and exert some degree of pricing pressure on theses fees. The Google / Apple duopoly means that this isn't working.
