In all fairness, I’ve had some really dicey problems on Linux. I think the most difficult problem I’ve encountered was when I bought a USB soundcard which only worked in legacy mode, but using Wireshark and the USB audio class specification I managed to track down the bug in Linux’ usb-audio module, so now I’m technically a kernel contributor :)
For me the difference is that when I get a problem on Linux, it usually tries to provide me with the information I need to figure out what goes wrong, and due to its open nature it tries to make it easy to fix things. Also the majority of the time, Linux is working flawlessly. Windows on the other hand, is plagued by bugs and annoyances that show up on a weekly, if not daily, basis. And when issues happen, they come with little information and are often impossible to fix yourself since the OS is locked down.
Tbh the majority of my FOSS contributions were to fix problems affecting me personally :) but I’m glad that they’re helping others too. This one is definitely the one that goes on my CV though hehe
