I say this mostly because the tech set seems OK with content piracy in a way that they wouldn't be OK with say, shoplifting. I don't see people recommending walking out with a pair of Airpods from best buy because of Apple's ethical breaches.
Most of us on this site produce copyrighted works for money. Many of us are pretty knowledgable about how copyright works, as it's an integral part of our livelihood. So please don't try to promulgate that weird media industry propaganda here.
Also, read what I wrote: "if you want to pirate, fine, but don't act like you're performing a noble act". What specifically bugs me is less so the act - I assume few among us haven't engaged in illegal streaming, paywall bypassing, password sharing etc. - it's the weird contortions people go through to frame piracy as a noble endeavor vs. just admitting they're being too cheap to pay for something.
Commit theft if you want, but be an adult and acknowledge it for what it is.
Clearly, they enjoy the content. You don't just stop enjoying things like that.
If you feel streamers are offering a bad deal, don't take them up on the deal and find something else to do. If you want to watch shows your friends and family are watching, take the deal.
