Allow me to reply, I think you've misunderstood parent's point:
- there is a spectrum of "importance" to software: a shopping app crashing is generally less critical than medical software crashing during surgery.
- there is a spectrum of "importance" to the news: surely the benefit and damage of reporting on Netflix's latest show is lesser than reporting on an incoming tsunami.
If you are warned upon fast release of a piece of news of "lesser impact" that it's "unverified", "untrusted source", etc., then you get to choose the impact: you either wait for further confirmation or act now, that's on you.
Conversely, for the "important" part of the spectrum, then we all agree that like critical software, it must be vetted and validated before release. There's no question about that.
As for where to draw the line, it's anywhere each particular new outlet feels it should be; but the mention of where we are on that spectrum should be at least industry-wide ethics for the Press, and enforced by regulation if necessary (see other comments for great suggestions about how to indicate trustworthiness of information, extent of research, sources, etc).
