Ransomware is something that affects people who do not have the basics of computer literacy anyway - which means that firstly they are not aware of what the Internet is, and secondly what backup is. It is easiest to blame cryptocurrencies for everything, but it is not the tool that is to blame, but the people who use it.
I would definitely agree with this. As someone who is working in the IT sector, we are made to undergo training on how to avoid phishing mails and trojans. And I believe that anyone with basic computer knowledge will be able to avoid such attempts. So first they need to analyze how the computers got infected with ransomware in the first place. How can they be sure that this was not an insider job? And perhaps the talks about targeting crypto may be a diversionary tactic to shift attention from these flaws.
