Even if coffee doesn't cost $5, and it costs $2.50, that's 4 coffees.
Or even $1 coffee, that's 10 coffees.
Unlimited music streaming for a month is absolutely worth 10 coffees.
The coffee example is brought up because _most_ people that claim that $120/year is a lot for them, spend a lot more than that a year on coffee.
That's not to say $10/month is trivial. I'm sure it's not a trivial amount of money for some people. The parent isn't denying that. They're saying that they're happy that Spotify is banning people that are trying to have their cake and eat it too. They're blaming people that CAN afford 1,2,5,10 coffees a month, and still chose ads or worse, adblockers for a service they can easily pay for as the demise of the internet. Which I wholeheartedly agree with.
