Your OP reminded me of something so after a bit of digging I managed to find it.
Back in the 70s almost all software was free. Freely developed, freely shared, freely transmitted. There was a core group of hobbyists who loved working with, on, and for computers and they collectively did some amazing things. However, their work was inaccessible to people who didn't know how to use a computer so it remained the best kept secret. Eventually, companies started getting patents for their software and the original hobbyists treated this new, patented software just as they treated everything else, freely used and freely traded. They were the original pirates.
By the late 80s, Apple and Microsoft forced most other small software developers out of business and had a virtual monopoly on the OS generation. That is, except for one group. The GNU Project was a continuation of that movement of free and fair use of software and was led by many of the original developers from the 60s and 70s. Despite attempts by Microsoft to control it, they are still strong and producing wonderful new things.
At the heart of this movement is the idea that if you put something on the internet, it should be free and unrestricted. Whether it be a song, a movie, a piece of software, or a video game, if it is on your computer you should be able to access it freely according to this movement. So while you might be at a complete loss as to why online piracy isn't viewed as a crime, it's because it harkens back to the days when computer software was freely used, freely accessed, and freely transmitted.
So, if you are sick of people pirating games, don't pirate. If you are tired of getting free software, then pay for it. If you hate people who pirate, write us a strongly worded letter along the lines of the original DRM dick: William Henry Gates III. I think the two of you have a lot in common.
