Back in the day, before streaming was a thing, there were lots of people saying that they'd gladly pay for content if it was served to them in a convenient way. But why would you pay for a worse experience (at that time physical media, often at lower quality, and lower availability) when you can get a better one for free?
Along came streaming. Lo and behold, piracy decreased. Where the fuck do you even go to pirate music anymore? All the big sites have shut down. Video piracy is kinda still going strong, probably mostly due to bullshit concerning exclusives, but it's way less than it used to be.
Its their platform, they can do whatever they want with it I guess, but this trend is definitely gonna be a big boost to piracy.
