I'm calling BS on this list. Pretty much noone makes any of these assumptions. The thing with many of these (eg VoIP, Google Voice, VPN etc) is that the population who use these for legitimate purposes is too small for most devs to care about given the cost of fraud from people who are using these things nefariously. Both type I and type II errors are important but they mostly only care about type II errors because type I errors just piss off a small number of good people whereas type II errors cost them money and if they go unabated will get them shut down by payment processors, banks, regulators etc.
