I remember having a similar conversation with my bank: I was suggesting that 
a 0.1% interest rate was, to all intents and purposes, a zero interest rate; 
they insisted on still calling it an interest-bearing account.

Of course, from their point of view, it was still returning an infinitely 
higher amount of interest than the zero-rated one, even after tax.
