There are still plenty of laws that are not in compliance with the digital age of the 21st century. Some laws only apply explicitly to hardware or physical or physically connected devices and you cannot extrapolate to get the law to apply from software standpoint. In some cases even “wireless” hardware such as a cell phone is legally different from a landline. One case is interfering with emergency calls being a Felony California if it’s a landline but a Misdemeanor if it’s a cell phone. That may be the basis for the drone thing but I’m just guessing.
