OK, but I’m not arguing for the sake of argument. What I take issue with is the overly negative point of view that isn’t justified by the reality of the current technology market. It’s limited, depressive and ultimately self-destructive.

Perspective matters. Money isn’t the only measure of success. Internet infrastructure is basically Linux, nginx and Apache - seriously, apart from user endpoints it’s pretty much all open source - and the most common endpoint OS is Android so also open source. The idea that open systems aren’t as successful as proprietary ones doesn’t reflect reality, it’s a projection of a limited point of view onto reality (it only seems true if large portions of the current technology market are ignored).
