Of all the images I have seen of the attempted coup, I have only seen baofeng radios. These are very cheap ($20'ish) radios that work very poorly (they splatter all over the bands) even when equipped with decent antennas. They barely work when equipped with the stock rubber-duck antennas.
It's easy to be a snob about the type of radios that they are using, but that's not even the point.
These people are idiots. Bringing their cellphones, recording video of themselves committing felonies and then posting them online. There is already plenty of rules regarding what can/can not be said using amateur radios. There is however no requirement to provide identification before you purchase an amateur radio.
Anybody can buy them, and it's based on the honour system to use them according to the law. It's already against the law to use them in a manner that is against the law.
Id' like to see this used as a punitive measure against everybody who was using them during the coup. Maximum FCC fine for all of them.
