When discussing tradeoffs, it's not about correctness but value judgments. Is it preferable for people like geocar to die than to continue allowing people to access all websites with arbitrary devices and software?
Of course, there are services that could be exposed through a website where the consequences of improper use would be catastrophic, but I would argue the web is usually inappropriate for control of life-critical systems without other safeguards or redundancies.
Might that apply to the software geocar credits with saving their life? Without knowing more, we can't say. There's a good chance it applies to things like running open source operating systems and browsers.
It also enables more software to be popular because it will be cheaper to run sites and sites can be more profitable that before.
