And I think this simple ignorance illustrates the looming problem for the UAV community. As a commercial pilot and experimental aircraft owner, I can tell you that if the UAV community does not start to self-police these types of excursions, either by education or with software solutions (like the GPS-limiter mentioned in the article), then the regulating bodies will do it for them.
Most HN readers would agree that there is huge potential for UAV technology, but one needs only to look at the glacial progress of certified aviation technology in both the US and Europe to see that over-regulation can and does stifle innovation.
For readers familiar with the differing regulations in the US for experimental category amateur-built aircraft vs. certified light aircraft, you've seen the wide gap between what is possible to do with technology and what is legal to certify. In most cases, an aircraft built in your garage is far superior in display and sensor technology than your average certified airplane. This trend has only recently started to self-correct.
The point is, US organizations such as the EAA and AOPA do a tremendous amount of work to educate their members and to lobby Congress to ensure that what limited freedoms we have are maintained. I think the UAV community needs something similar or their industry will get regulated to death -- especially after the first drone gets ingested into a jet engine.
