Freedom -- that's what it is. There are now more and more cases where we don't have to ask for permission.

Unfortunately, as I look around, I see most of the hardware vendors around me as gatekeepers. They prevent me from writing custom code in various ways. Apple restricts access to NFC or their UWB positioning, Supernote Manta does not let me access a bluetooth microphone, the list goes on. Denon at least has an API in their amps/receivers: buggy, but it's there.
