I switched to linux in 2004 or so. All those old use cases kind of vanished or changed. Perhaps the subset of software is more limited on linux, since Microsoft also builds - and exploits - a platform for commercial success, but I see more and more linux-specific applications too, typically using qt5 or qt6. Which is interesting considering linux does not have a huge share here. I guess there does exist some market value here.
I just can not really see myself using or needing "warez" on linux - the use cases are sooooo different now. For multimedia there are very few use cases not covered by ffmpeg and mpv. The only thing I'd like is something like avisynth, but more like a domain specific language that is even shorter. I remember back in early 2004 or late 2003 I was still writing avisynth scripts to modify video data on windows. Linux pipes never really went into an object-oriented approach and view onto data.
I remember switching to Linux around 94 and at the time one of the things that annoyed me was that there was very little commercial software to patch registration checks out of!
There were a couple of image-viewers, and similar things, but I fell out of the habit of decompiling random binaries, and stopped keeping up with the newere techqniques for a good few years. My reversing skills came back, later, but swithching to Linux where everything was "free" and source was mostly available really did change a lot of my computer-related hobbies.
