Many things are named after Robin Hood. It's not as though the brokerage invented the term or has any right of exclusive use. You'd have to be quite dim-witted to muddle up a brokerage and a load balancer.
Many things are named after Robin Hood, but I only know of two things specifically calling themselves Robinhood and one of them I only learned from this thread.
In fairness the load balancer presumably came first, but the point remains.
