So something that is used to develop something that later generates billions of dollar of profits isn't, in itself, responsible in part for those billions of dollars ?
So by this reasoning, something like Linux has exactly $0 value in monetary terms. Linux is never an application, it never does something that actual users pay for (the "users" who pay for Linux support are just developers and corporations who use it to develop something else).
>I also don't think you understand what profit is and the difference between profit and revenue.
Yes, I don't understand an elementary distinction between terms that anybody with a dictionary understands. This is quite a fair and productive point for you to make.
>this exchange has become pretty pointless.
Probably the one thing you're right about in this, I'm indeed not interested in debating incredibly insecure people fond of accusing others of ignorance (quite often a projection technique) instead of engaging with their arguments or citing specific examples or research.
