I am guessing they recognize they lost the war!
In the last week, Bloomberg negative coverage for bitcoin was obvious, but in the last 72 hours, multiple positive articles, and news been released.
Yeah that's only because they can clearly see what they were saying was either completely wrong or turned out to be wrong. And now since the price is increasing they need to address that. I don't think Bloomberg was covering negative things about btc purposely, it was probably a correct decision given the drop in price.
