Will this increase the cost of Bryston products, i.e. does Bryston have to pay Apple to decode Apple's proprietary formats? That's what I don't like about Apple--how is their format better than the open source FLAC format for hi-res? I'm pretty sure the answer is: it's not better.
AAC is not an Apple proprietary format. It was developed by Fraunhofer (who invented mp3) as the next-gen replacement for mp3 but never saw wide adoption. Apple does not own the codec.
As for Apple Lossless, it uses the same 'container' but different compression parameters that support fully lossless decompression. Apple released the source code in 2011, so it isnt 'proprietary'. It is freely usable by anyone.
Agree that it is no better. It is also no worse. I too wish they had just gone with the ubiquitous FLAC though.
