Ambedkar inferred the Mandal’s real aim was censoring his address, not saving money

Evidence

Whatever be the truth, I did not yield to this pressure. But even when the Mandal found that I was insisting upon having my address printed in Bombay, instead of agreeing to my proposal the Mandal sent me a wire that they were sending Mr Har Bhagwann to Bombay to “talk over matters personally”. Mr Har Bhagwan came to Bombay on the 9th of April. When I met Mr Har Bhagwan, I found that he had nothing to say regarding the issue. Indeed he was so unconcerned regarding the printing of the address—whether it should be printed in Bombay or in Lahore—that he did not even mention it in the course of our conversation. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 770
