What I’m saying is that I actually like the mute button and I don’t understand why some are so upset about it. Your post doesn’t help to clarify other saying you already have an addon that serves a similar purpose.

And I don’t want to have to install an addon just so that I can find and mute/close some random tab that’s playing unwanted sounds.

Could this be some kind of tactic to manipulate the crypto market?

You don’t “rival” the Steam Deck with better hardware alone.
