I am a ham radio operator and I can tell you first hand that it creates a vast amount of noise. Sure it's super annoying but what worries me more is that HF frequencies used by the various coast guard organizations and by trans-oceanic flights are also affected. That scares the crap out of me.

Its true...companies can benefit...look at the ever-so-hackable WRT54G and GL Linksys released another version that supported being hacked...they made a lot of money from "hackers" Alll tho they have lost money on other hacks such as the Linksys PAP2 which sells for next to nothing...this is costing Vonage more than its costing Linksys but you get the point
