^ this is the best explanation I've seen so far in the thread.
Software translates directly into money. The company I work for makes physical devices - they have all kinds of engineers, but what we're making goes directly into making the company money. Like I can straight up say, they make millions off the stuff we produce for them.
If your work makes the company a lot of money, it's not frivolous to ask for a small chunk of it lol.
