Not everyone has the option to turn off from certain technologies. My employment requires me to use social media websites (but I can choose to block ads on them)
Piracy of MS office doesn’t impact Microsoft much because Microsoft is primarily a cloud and enterprise IT company. For Netflix, Spotify and Disney, piracy would have a meaningful impact. That’s why Netflix cracked down on password sharing.
Piracy isn’t mutually exclusive with supporting your favourite artists. You can still go to concerts, buy merch, donate or buy physical media. I pirated three of Supergiant’s first three video games, and then when I was earning, I bought the games again and played them because of how good they are. Now I buy their games on early access every time.
This is a long discussion now, and answering everything point by point will be a lengthy exercise.
I’ll say this: I believe in a world run by corporate interests, piracy is similar to civil disobedience. If we collectively decide to create friction to the functioning of the system, it can in combination with other ways of resistance influence the situation in our favour.
