I have taken this from the book Urdu/Hindi: an artificial divide : African heritage, Mesopotamian roots, Indian culture & British colonialism by Abdul Jamil Khan. The book is a compulsory read for those interested in Hindi/Urdu.
According to the book, the above comments were made by Firaq Gorakhpuri in an interview that apparently did not come out in public domain. Firaq uttered those words referring to all those who worked towards the disappearance of Urdu from schools after the Partition.
The sad aspect in those days, and even now was/is the compartmentalisation of Urdu/Hindi with religion. For several decades Urdu was spoken and learned by the people of India, but took a backseat in later years.
One could see Urdu posters/banners in the background in many of the early Hindi black and white movies. In later years, I believe Bollywood has played a role in its own way in getting the common masses acquainted with Urdu words. The posters though are nowhere to be seen, neither in the films, nor on the streets.
