> it's not the tech companies' fault that it's perennially underfunded

This is simply wrong in a lot of cases. Tech companies absolutely use their immense wealth and influence to alter public policy and spending. Regulation and budget decisions happen all the time to benefit a specific company or industry, at the expense of the overall public. Tech is hardly alone in this, but that industry has more money and mind share than most, and correspondingly more ability to change policies to their benefit.

The more money and hype a Disability Dongle company gets, the more interest and ability it will have to degrade less shiny but more effective alternatives.
