1. These neighbors have been arguing with each other for a long time. Snow removal was just part of it.
2. They live on a very narrow street where many of the homes on one side (where the Goys lived) have no garages. Some of them have small paved areas in front of the houses between the house and the street that are used for off-street parking. If you have a deep snowfall there really isn't any place to put the snow.
3. I'm not so sure that these two were dumping snow on "Spaide's property." You can't really see this in any photos from the news story because the ground is covered in snow, but the front of Spaide's lawn ends in a retaining wall that fronts onto a small paved area that runs alongside the street in a place where a sidewalk would usually be located. You can see the wall on the right side of the photo below. I'm pretty sure the area in front of the wall -- where the Goys were probably dumping the snow -- is actually part of the street right-of-way. I say this because if you look at a street view of the area, you'll notice that the utility poles along that side of the street are located about 10-12 feet away from the edge of the street pavement. Also, you can see that the other homes on that side of the street have lawns that extend to the edge of the pavement, but any fences in front of those other homes don't run along the street, Instead, they line up with the retaining wall in front of Spaide's house.

You’re correct. If the area in front of the retaining wall next to the street was part of the guys property, he certainly could not be harmed by placing snow there.
Well, there is the issue of just where the gov’t snow plow truck is going to push the snow as the truck moves along the tow sides of the street.
Best not to put your snow where the truck is going to push it across the front of my already shoveled driveway.
Common sense.
