Huh? How is "responsible disclosure" related at all?
It's acceptable to cut corners and ship shoddy software to consumers, because if anyone points out the flaws, they're being "irresponsible". The responsibility to protect customers is therefore shifted away from the vendors onto researchers. Pretty sweet deal, because good quality security engineering is expensive!
The people that I know that works in security research treat responsible disclosure as "you have X time to fix it before we tell the world", to give them a chance to fix things before everyone, with who knows what intent, gets to learn about the issue. There's always a time limit and then its released regardless.
I have never once seen someone say that it's irresponsible for security engineers to point out flaws in software. Indeed, "responsible disclosure" often includes disclosing bugs even though they haven't yet been fixed when the developer isn't responding. There are problems with the term, but this isn't one of them.

I've got news for you, it happens all the time. I can't open my mouth without some Microsoft lackey shouting irresponsible at me.
