PARIS (AP) Telegram founder and CEO Pavel Durov promised to step up efforts to fight criminality on the messaging app, his first public comments since French authorities handed him preliminary charges for allegedly allowing the platforms use for criminal activity.

In a Telegram post late Thursday, Durov defended himself against the French judicial investigation, suggesting that he shouldnt have been targeted personally.

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.
