Blind people in my family rely on proprietary software for dealing with visual impairments. It's painful and offensive how exploitative these tools often are. The thought of installing something by a similar company into one's body is frankly dystopian.
I would gladly pay big money for proprietary tools if it means regaining some of my sight until libre options exist. Looking at the rather sorry state of accessibility on libre software, I'll be dead and buried before the first digital eyeball with free software comes out.
The most expensive IT failure in our governments history was healthcare related.
It's typically $10-$50 per visit. Maxes out at $130 per year.
This probably weeds out a lot of frivolous visits and keeps the system healthy.
