Talk by CD Projekt's CEO about not using DRM, and dealing with piracy: https://kotaku.com/some-real-talk-on-piracy-from-a-witcher-3... Their approach always made so much more sense to me.
I pirated the Witcher 3 originally, but it was so good I ended up buying it just to support the company. Step one in stopping piracy is to make something actually worth paying for.
In argentina, people pay netflix and share accounts between friends, and some play hbo go for GoT, but thats it. In the U.S., its very rate to see pirated TV.
A sandwich might be worth 5 dollars to you, but if there are free sandwiches next to it, you will think "I would pay it if it were worth it"
