I wouldn't condone vandalism -- despite however justified you may feel it is, plus it would have the opposite effect: I don't want whoever create those demon machines to know we know where the mute button is.

Vandalism is actually cool and good, especially when employed in the fight against these ridiculous intrusions into attention and minds.

This is why I would suggest a baseball bat rather than pointing out where "mute" is. Bonus: effective against the angry property owner as well!
