Really weird how the governments and tech companies always go after victimless crimes but in the instance of fraudulent tech support where there are real (mostly naive and tech-illiterate) victims they do nothing.
Devil's advocate. Maybe it doesn't seem like a big problem to those you mention since most of people scammed don't report it? But the prevalence should speak for itself, and this cancer feeds itself.
Who takes care of a crime if the perpetrator is in a different country or online?
