Its all about the name Chennai

Most of today's Chennaiites / Madrasvasis have been believing that the city's name was 'Restored' to Chennai reversing what the British did. But, here is what I found out in a radio debate I accidentally tuned into on the way to work today.
Chennai, formerly Madras, was originally a fishing hamlet that went by the name 'Madarasapatnam' a hundred or so years back.
It gained prominence when the East India Company, the erstwhile proxy front of the British Government used to colonize the south asian countries, bought a piece of land that is now called Fort St. George, from a local ruler.
History has it that the local ruler agreed to sell the land to the British and imposed one condition for the sale. He requested that British to name the city there were going to develop after his father and former Rajah, Channapa Naicker(Naickan).
The British, however did not honour their agreement and went on to refer it as Madras as short form of referring to Madarasapattinam.
The name stuck for hundreds of years until one day when the Chief Minister of Tamil Nadu Mr.Karunanidhi (also known as Dr.Kalaignar ) issued a G.O renaming the city as 'Chennai' claiming that he was restoring the original Tamil name to the glorious city and we all believed him!
What I found unbelievable was that this Channappa Naicker/Naickan, never visited this city and had nothing to do with its existence and survival, leave alone developing it to be a cosmopolitan commercial hub.
Why should we name our city against a non-entity? I find this unacceptable as a proud citizen of this country and city.Why should I call my home by a name of a person who meant nothing to this city?

Much to my disgust, the radio featured a youth Congress leader who was making inane arguments about how we are changing everything . He was referring to IT growth and changes in Financial sector, and he was accusing the general populace for not willing to accept a change in the name of the city. I cannot fathom what is the connection between IT sector and the name 'Chennai'.
A research scholar was trying in vain to counter his arguments by explaining that she had nothing against change that is meaningful , but the youth congress leader would not listen to her and was just sticking to yelling unrelated arguments about how even in court they have started referring to the judge as 'Your honour' killing the British practice of addressing the judges as 'My lord!'.

I do not know if it is worthwhile even spending time and effort in discovering the truth and making a movement. Do I need to change it back to Madras?
I live in a world where a child's parents' names keep changing, the workplace names keep changing, the lanes and roads are being constantly renamed, products are being rebranded, even planets are suddenly being declared as just a piece of rock.
Frankly speaking, I dont care any more by what name my city is being called, it just will be 'home' to me.
