Several software products make statements about possible prosecution, for example Microsoft Office:
Unauthorized reproduction or distribution of this program, or any portion of it, may result in severe civil and criminal penalties, and will be prosecuted to the maximum extent possible under the law.
How close is such a statement corresponding with the reality?
They claim that certain actions will be prosecuted (instead of may be prosecuted), what appears to imply they will surely start the prosecution.
...to the maximum extent possible under the law... – this appears to imply that the actions taken on their side will reach to the maximum extent they are able to achieve.
Based on the language used, both points seems to sound almost like obligations from company side.
Isn't this language misleading? For example, for proven single piracy act on single $400 software package, will the company surely start prosecution and will work on reaching "maximum extent possible under the law"? Given the damage, such an extensive action could appear cost-unreasonable for the copyright owner (except of possible publicity effect) and my question is why such a strong wording is used? Is it realistic? Or is it a part of law traditions? Or what else has to be noted there?
