The phrase in the title is a common trope that comes up when VPN services are discussed. While this statement is technically correct, it can be misleading, as it implies that all providers handle law enforcement requests and prepare for worst case scenarios similarly, so their conduct cannot be a differentiating factor when you evaluate them.
Been using them for many years and several instances I leave permanently connected. I can’t recall a single instance of AirVPN disconnecting from their side.
