Yes, we can all make long lists of open source projects. That's not my point. The point is that the average person, on an average day, is using lots of proprietary software (or proprietary forks of open source software).

I've been hearing about how the future of software is charging for support tickets and hand-waved 'integration' for 30 years. The biggest, richest and most powerful tech firms today all ignored that advice. There's only one company that did well out of that approach and they're now called IBM.
