this answers the question pretty comprehensively i think. https://theterminalist.substack.com/p/bloombergs-7-powers-an...
Oh, cool! An antitrust violation epitome!
It could be if they were the only one trying to offer this, but because it's so expensive, there are always multiple competitors trying to pick off their users. And when the next round of corporate cost cutting comes, they always come for the Bloomberg terminals, trying to push something cheaper.
But the cheaper alternatives are always inferior too (never mind the decades of muscle memory on Bloomberg).
Despite the price Bloomberg has maintained its number one position. I think in no small part that's also because their customer support is absolutely excellent. Press F1 twice and you're in a chat with the helpdesk; these days the initial query is triaged by AI of course, but for actual issues you're talking to a real human in less than a minute (sometimes just seconds), and these real actual humans typically have the expertise to help you. If not, the higher levels of support are good too. Don't underestimate this aspect!
But one of the Bloomberg’s main selling points, at least from the last discussion I’ve read on HN (and some of the comments here too), is the chat, which means there’s network effects at play. So you can’t just build a better terminal, you also have to convince the majority to switch.
(Though apparently Bloomberg Chat also supports email? Maybe the competitor can use that to interface with it, so it’s only “green bubble” bad, not “all your colleagues are there and you’re not” bad.)
The network effect is real and I don't think you can interface external email with it. You do get a Bloomberg email address as a user but I've never seen anyone in a chat with an external email only.
