There are several reasons for BB making it so very hard to use their system.First is just simple incompetence. Although BB is effectively 1980s technology, (with some that is 1970s), it's remarkable that Reuters whose technology base is vastly older is far more up to date.Second it's a defensive move. By not documenting BB, it is very hard to clone it. Personally I'd sack on the spot any techie reporting to me who did things the BB way, but replicating all the bizarre ancient structures would cost a lot of money.The other defensive aspect is that now that so many front office people have invested lots of time in it, they are reluctant to do the same with a better interface.The training is free because BB wants to keep close contact with it's users/victims, and wants no voice other than it's own to have credibility.The technology is kept broken because Bloomberg is following the classic Apple approach rather than the Microsoft view.Apple and BB regard any money made through their products that they don't get as stolen, and yes they use that language.Thus Apple and BB keep things secret, and attack anyone who tries to make addons.Ask yourself why given the vast number of highly expensive users of BB, there are basically no 3rd party products ?Microsoft works on the principle that the more money people make with their products, the more money they make.Until I asked them to do it download-only Microsoft used to send me a copy of every damned development tool they make (from VC++ to building Outlook addins in simplified Chinese), and they insisted on buying me a very expensive lunch as well. BB on the other hand lied to me repeatedly about how their stuff worked, refused to handle documents, deleted documents, denied their existence, and repeatedly changed specifications in a pattern that I could only interpret as malicious. At one point I could only get phone calls replied to by cancelling BB terminal rentals, until I got a call back.
