He really hasn't done either of these things. Oborne has been his own man for as long as he has been in journalism - he resigned (when Political Editor) from the Telegraph over them selling their editorial line, and has written numerous books, articles and reports about what he sees is the crisis affecting modern British politics. (edit) He also wrote the best article you will ever read about the 2011 riots, which appeared in the Telegraph of all places:

He has also given Corbyn a much fairer hearing than his employers for years (without ever being pro-Corbyn) - take a look at this interview for instance:
Or this article about Corbyn's foreign policy:

He is god-awful at predicting things, though (in fact the only prediction of his that looks like it is coming true is his claim in the mid-2000s that the political class of the day would eventually lose power and be replaced by either demagoguery or someone who would restore British politics).
