Do you even know what "verbose" means? Haskell is obviously the exact opposite of verbose. In fact some more verbosity often makes it easier to understand.
In context, the "language" GP was referring to was the (presumably English) language in crypto currency white papers which is "needlessly convoluted and verbose". This was being contrasted with the concise language of the original Bitcoin white paper. It's not about programming languages.
Also, another possible reason is that many crypto people tend to confuse complexity with ingenuity. While the bitcoin whitepaper tries to make a complex topic as simple as possible, a great many crypto companies and people purposely use language that is needlessly convoluted and verbose.
Perhaps they're doing it on purpose to seem smarter?
