Governments have frequently laundered the surveillance state as "child protection" laws, pushing for a cozy relationship between companies with data and cops et al. They want the ability to snoop more or less whenever they want and will push in that direction. This kind of relationship is not just for cops, though. The same companies also gladly work with and hire people from intelligence agencies to craft narratives and manipulate sentiment. When a company doesn't play that role as well as feds want, the hammer comes down (TikTok, Telegram).
Though really, the actual question is why they are writing this article and why now. The answer is that Durov has been arrested and the author is attempting to justify it by piling on "Telegram is bad" claims while avoiding discussing the actual legal basis and evidence around his arrest. You will also note the sources used in this article are entirely government officials and NGOs in the constellation of NGOs that work directly with the government - or are unsourced stipulations. No academics were cited, nor free speech advocacy groups, or even lawyers.
