Gary Hoffman has hit out at City Director Leonard Brody.
The Canadian entrepreneur has had a mixed reaction from City supporters over his tweets and many have accused him of side stepping questions that supporters should have a right to know the answers of.
Speaking to the CT, Mr Hoffman who has cited one of the reasons that he left City's board as a lack of communication, said: "I applaud saying more to fans about what is going on but the transparency has been extremely selective.
"There has been lots going on that they have not been transparent about. For example, there was too much mortgaging of the future which is a bit like buying your house on a credit card - ultimately, it has to come to an end. I won't go into detail but I objected to it several times.
"Superficial tweeting does not help either - it just gives a sense of keeping in touch but hasn't really kept people up to date with key developments off the pitch."
