I find it strange that so many cryto people get so emotional when such comments are made. It makes it rather difficult to have an actual discussion on the issues.
I can rephrase as a question: Should we stop using groundbreaking and individual-empowering technologies just because some criminals benefit? Every single technology is exploted by criminals. I fail to see how that is an argument for its disavowal. If anything, we need to normalise privacy and encryption among virtuous everyday individuals.
