In a Telegram post, Durov defended himself against the French judicial investigation, suggesting that he personally should not have been targeted.
"Using laws from the pre-smartphone era to charge a CEO with crimes committed by third parties on the platform he manages is a misguided approach," the post said.
"Building technology is hard enough as it is. No innovator will ever build new tools if they know they can be personally held responsible for potential abuse of those tools."
While insisting that Telegram is not "some sort of anarchic paradise", Durov said surging numbers of Telegram users "caused growing pains that made it easier for criminals to abuse our platform".
"That's why I made it my personal goal to ensure we significantly improve things in this regard.
"We've already started that process internally, and I will share more details on our progress with you very soon," he said.
Durov, born in Russia but now a French national, was detained in late August in France amid an investigation into crimes related to child pornography, drug trafficking and fraudulent transactions associated with the app.
He said the investigation into the app was surprising in that French authorities had access to a "hotline" he had helped set up and they could have contacted Telegram's EU representative at any time.
