Nintendo is a special case. Their entire business model is based around their first-party games only being available on their systems. As a result, piracy is a much much bigger threat to their business model than it is to anyone else.

(Beyond that I feel that there’s a cultural thing where the people calling the shots at Nintendo just hate piracy a lot more than most other companies - they’ve always been weirdly aggressive about it. But it’s not totally irrational - they really depend hard on games like BotW only being available on their systems.)

As Gaben said, piracy is a service issue.

Streaming sites are a bigger issue because they’re so easy to use, to the point where it’s often easier to just view something on an illegal streaming site than to view it on Netflix. You can email your grandma a link to a torrent site and she can use it immediately. (I’d set her up with adblock first, ofc. But everyone should be using adblock.)

Meanwhile torrents, for people who aren’t already set up to use them, are hard. You can’t just email your grandma a link to The Pirate Bay.

Microsoft has always had a strange relationship with piracy. They’d obviously prefer everyone pay for their software, and will crack down on stuff that seriously threatens this - but at the same time, their real power and profit comes from their monopoly (well, came from their monopoly; things are weird now due to their failure to win the browser wars and mobile device markets.)

If the alternative is you using a competitor’s software, they’d prefer that you pirate windows.
