Bloomberg is also aggressive in retaining customers. A few years back, there was a scandal where Bloomberg News reporters used Terminal data to see that a target of their news story had not logged in for a bit and wrote about it. Since this was breach of trust between the two parts of Bloomberg, many of the banks starting looking into alternatives for BBG chat, and Bloomberg responded by offering the banks (their existing customers) many discounted terminals. Which seemed to have worked since the scandal died down and their chat is still the leader in wall street communication.
