For those who aren't aware, there is a bit of controversy in the ham radio community at the moment around Winlink. The tl;dr here is that a bunch of boaters started getting ham radio license so they could use Winlink to send and receive email when they're out at sea.
The problems started when a few of them started using it for more than personal use - they were using it commercially. This is strictly prohibited with ham radio. This is compounded by some of the boaters not using it properly; they'd use it on frequencies already in use by others at that time.
