Several years ago, the Channels app (an Apple TV app that works with the Silicondust TV receivers) implemented an ingenious way to invoke the “Mute” feature by giving the Siri remote a quick and rigorous shake - no dedicated button required. This magical feature works 100% of the time and is very Applesque in its ingenuity, fluidity, and simplicity.
I asked the Channels app developers if they had patented the feature, and they said that they weren’t going to, inviting others, including Apple themselves to implement this idea system wide on the Apple TV. I then contacted Apple and encouraged them to implement this feature system-wide, which would solve 1/3 of all complaints about the Siri remote. Apple, in their infinite wisdom, completely ignored my suggestion as well as the appeals of the thousands of their users for a “Mute” feature to be implemented.
Apple think that they know better what we, their customers, need and what we don’t need. Accept this as a fact and make your future technology choices with this knowledge in hand.
