Bloomberg has information about what you're looking at as well (far more than just stock info; a wealth of information about just about every market & market-relevant news). If you can tell what someone is looking at you can easily infer they have a position in that market, which is very valuable (and very proprietary) information. Furthermore you could look at overall flows and make decent predictions about, eg, future volatility. It had been speculated that Bloomberg employees were looking at the actual content of searches, which would be a death blow to their reputation as a trusted platform. This story is Bloomberg saying "Yes, we gave access to info to employees we shouldn't have, but it was actually pretty banal."
