If people are suffering from subscription overload, they could be less likely to consider a Bloomberg subscription than they would normally.
I get that for most people a Bloomberg subscription will never be on their radar, but between those people and the "must have Bloomberg" crowd, there will be a grey area of people who would really like to have it and can't quite justify it, to those who are sort-of interested and might get around to it if other things in their life align. Those are the people Bloomberg is working hardest to get to sign up. Therefore, if subscription fatigue is showing up as a reason that their subscriptions aren't growing as much as they'd like, looking into questions like "is this a problem?" and "what can be done about it?" is entirely within their wheelhouse.
It's not like Bloomberg is one of the subscription services that have popped up in the last 10 years. They're a "legacy" org at this point.
I see this all the time when news agencies decry privacy on the web, yet their websites are often one of the worst examples for any kind of digital privacy.
