It is a good thing that irrelevant people like you aren't in a position to make any important decisions about anything.
Likelihood of a law-suit being filed in this case is determined by the evony people - it is either 0% or 100% because it is a binary question of whether they file or not. Now likelihood for winning is a totally different story; let's just say there isn't a precedence for winning cases where a company sues its customers....
As for the other company you mentioned, you really should look into what you are posting for relevancy before you do so. That case has no similarities; in fact the case was brought forth on commercial grounds that the defendant was infringing on the plaintiff's intellectual property for profit. In this case, the programmers have released the code 'open source' so there is no commercial grounds for infringement.
If you had a clue you would know this and not have posted the misinformation that you did. In fact, misinformation being posted on legal matters is in fact a criminal offense in some jurisdictions itself o you may just want to find out for future reference, especially if you live in the US.
And to cut people off at the pass, DMCA isn't enforceable outside of the US, nor is it even able to be tried in court these days since the entertainment industry has plugged up the court system for the next 12 years.
