I don't mention them to encourage people to attack these people, but it comes off as a bit selective to focus on the people using your language for cryptocurrency when it's also used heavily by traditional fintech companies, as well as defense contractors, and even for large retail chains (Target uses it for data analysis). Facebook also uses it for their spam detection system. Why are all of these uses fine and cryptocurrency is not? And if they also aren't fine, then how should we solve this problem? Start non-profits/charities that specifically use Haskell, and somehow make those the majority of the available jobs that use it? That seems pretty infeasible unless you want to solve the broader problem of these jobs existing in the first place.
