I'm glad your frequent travels are eased through customs to the point where you don't see what happens. But allow me to suggest that a frequent traveler through one port once a month is an insufficient data set from which to draw conclusions?

If nothing else, you have available the fact that a software vendor sees sufficient demand to invest in this feature, to go along with your google skills to find counterexamples to your experience.

The US has a long history of this tactic, especially with issues that touch on law enforcement. The lack of decent data on killings committed by police is well-known; categorical refusal to allow studies on various drugs is too. But this is a frequent problem; hammering on killer cops with video is provoking grudging, slow change on the first and incremental legalization of pot is changing the second. But there are lots of issues over which this happens.
