As I said in the post about the Telegram Bot (#171665), most of the big players are afraid of using something that cannot be traced by chainanalysis precisely because they are afraid of not being able to verify whether the coins were or were not used for something illicit, and consequently being judged as interceptors of illicit money and paying court costs to prove their innocence. Now, it's interesting that small establishments don't care about this, because they are the ones who will usually benefit from not distinguishing the currencies they use.
