Similarly here. It is not about the act of people listening to the music for free. If this was a problem, a musician would just restrict access to those tracks. It is about a spirit of taking without giving back, which could be understood as: "Haha you idiots, thanks for providing it for free, I am not paying then". A bit like stopping to watch a street performer, and instead of clapping and (eventually) tossing a coin going like: "We are in a public space, I don't need to pay, idiot. Your own fault!".
Technically correct, but ethically wrong and shows they don't value the work of artists. This is just about words and showing some respect, not about money. And since words and showing respect literally cost nothing this makes the insult even greater.
Ethically wrong to watch a street performer but not toss a coin? I do agree that it is ethically virtuous to toss the coin, but ethically wrong not to? I'm not seeing it.
I am not saying anyone who listens voluntarily for 30 seconds and doesn't pay a handsome amount is a monster. What I said is that listening, enjoying it and then telling them: "Stupid musician, their fault for giving me the choice to pay, so I don't" makes you a bad person.
There are a thousand ethically sound reasons why you wouldn't toss a coin, you could not have one, you could be broke, you could misunderstand the situation, you could have a cultural background where this is uncommon and street performers are getting their share in a different way etc.
But enjoying the fruit of their work and then maligning them for giving it to you for free is not only rude, but yes: ethically wrong.
