So long story short he created a supply company with dedicated customer support, but his prices were correspondingly higher (those extra salaries have to come from somewhere). Most people just went with the cheapest option every time, one of the reasons that business failed.
This is ultimately why consumer protection laws exist. A person is smart, people are stupid and "the market" can't be expected to always act in its own best interests.
If I told my cost center that I went with a more expensive vendor because "they were friendlier", that would pretty much open an investigation...
Guaranteed.
Would the people championing this idea be willing to pay $10/month for their Hacker News account because the company was obligated to provide real human support to everyone?
Or $10/month to GitHub just to be able to have a GitHub account?
Or if you plan to start a website or internet company, do you really want to have to put your personal phone number on the project to comply with such a law?
They may not make money hand-over-fist but I bet there's enough need for the service that it would be self-supporting.
