It's possible that there is a good reason why that mechanism is not already more powerful.
This is completely blind speculation. It's also possible, using similar blind speculation, that this pathway is the virus panacea we've been waiting for, and that it will ultimately prove to be the death of all human-susceptible viruses ever. Take THAT, HIV!
But if the media has such a problem with that, maybe they could actually focus on that instead of praising Apple all the time, or conflating the issue with security exploits; or maybe give some coverage to the more popular platforms (Symbian, RIM, Android) that don't need to be jailbroken, instead of the overwhelming coverage of Apple all the time.
With the exception of right wing political media that get together for weekly talking points, "The Media" doesn't collude together for a common focus. Most reporters know next-to-nothing about the beat they cover unless it is a personal passion, and expecting them to dig deep is incredibly naive, especially in a time like today when a skeleton crew covers virtually everything.
You have people like Engadget saying "hooray, we can root our iPhones!" and you have people like CNet saying "iPhones are hot shit!", and then you have every tiny tech beat for every newspaper in the country creating stories from that and the massive wave of popularity Apple has garnered. I'd love to see more non-specialty reporting on the history of locking down devices, but you'll have to wait for someone like Wired (who, despite their flaws, is a news hybrid) to try to cross that bridge first.
If you think the system is working, ask someone who's waiting for a prompt.
