The whole point is to temporarily break a server someone's paying money for.
I'm not taking sides here, it just occurred to me that portraying DDOS attacks as definite cyber terrorism is a problem in the discussion we have today and I think it's a slippery slope, similar to the "piracy" argument we hear so often.
The problem with getting worked up about DDOS is that it isn't technically possible to make a clear judgment from it - that's what I was stating. Let me put it like this: A real-world protest can be thousands of people standing in front of a building and thus making it hard for them to do business or it can be smashing in their windows. A cyber protest can be linking thousands of people to an article on a website that you don't like and reducing their quality of service - or it can mean causing their servers to melt.
There are shades of gray in this discussion that you exclude and it is not doing the nuanced point that Stallman was making justice.
