The big issue in my opinion is that movie execs have this misguided belief that if you stop people from pirating your content, every prevented download will turn into a sale at full price.

But I expect that people will simply stop watching mediocre movie and low-effort series. Or wait for rebates, like those people who avoid cinema and then rent the bluray later. As a result of this misunderstanding, they try technical solutions and the effect is that probably every 2nd person who reads this has Sonar setup to fuel their "web-dl subscription" to Prime. The correct solution would be to lower prices (and that somewhat includes less ads) to make it more attractive to pay for that content. And they will need that strategy anyway to survive a direct competition with Disney = the Marvel cinematic universe.

I myself cancelled Netflix when I noticed that none of the people I talk to regularly care enough about their Netflix shows to remember the story... And from that I concluded that it must be mostly filler content.
