If the cryptocurrency weren't useful for criminals, scammers, and money launderers, then it wouldn't be useful for political dissidents either. The reason the undesirables use those technologies is because they work. Yes, bad people are going to use effective tools. Does that mean nobody should have them? Granted, I wish they would have just implemented Monero instead, especially since MobileCoin was (is?) unusable in the US. I agree they definitely could use some work on the backups side of the house as well.
