Boycotts are one of the most powerful ways an collection of individuals can express their displeasure with a corporation. I believe that they're heavily under-used and that people should follow through with their promises of boycotts far more often; I could be wrong but almost all legislation that the government brings up dealing with the negative side effects of corporate actions could have easily been handled through organized boycotts.
With that said, the "Ubisoft Boycott" can not really be called a boycott because (for the most part) people are not choosing to not buy a product they were going to buy as a way of sending a message to Ubisoft; all of these games that people are refusing to buy wouldn't have been purchased by these people regardless of the actions of Ubisoft.
