I was in Hong Kong last week. The cabs are indeed cash only, making it extremely annoying to take one as a business expense.

Ubers were everywhere and most certainly not outcompeted as you suggest, the longest I had to wait was 4 minutes. With a huge expat community not everyone can speak Chinese and being able to input the address ahead of time skipped a lot of mucking around with translation apps when a driver can't speak or read English.
