Note that any "opinions" found on a list such as this have zero validity - anywhere. They are just opinions. If you want a LEGAL opinion (which is still "just an opinion") you need to consult a Lawyer in your native country who is familiar with the "speciality" involved. (I.e don't ask a Real Estate or Divorce Lawyer about Computer law.)
I am more worried about what Microsoft would have to say if i was
ever identified as using software from them and not having windows ,
you see i live in romania and our law system is incompetent ... but
a lawsuit from Microsoft is a different story :P
Not really. Any lawsuit is totally dependent upon the vagaries of the law, and its interpretation and enforcement in any particular country. No lawsuit from Microsoft in the US would have any validity beyond the law system of Romania.
i just don't like risks for example another related question is ,
would Microsoft be able to see what we do on our pc's by using
software installed in crossover,
The "simple answer" is -- yes. Such monitoring software is called a virus or a worm. It can be installed on any computer with any operating system/software installations. Is such an occurrence probable? Not very. How does that software get installed? The same way any virus or worm is installed on any computer.
there are 2 big questions here each important ''is it legal'' and
''would Microsoft ever notice'' , again this is a serious concern if
you take a look at people who Microsoft stepped on in the past like
those 3 chinese guys who got 3.5 years in prison and 145 k $ fine ,
its rly not something good to do.
I am unfamiliar with the case you are referring to. Did prosecution happen in China or in the US? "Trafficking" is different from "Using."
In general (in Western Law), there are two "legal" situations -- Criminal and Civil. Criminal legal situations result in Fines and Prison time. Civil legal situations result in payments by one party to another in the form of "restitution" or "settlement." By their nature Civil "prosecutions" cary neither jail time nor fines. A private entity, such as Microsoft, cannot bring a Criminal charge against anyone. Only a "state" prosecutor can do so can bring a Criminal charge, and the allocation must be a violation of a LAW, not of, for example, a Copyright infringement. [A private entity can file a "complaint" with the state, but the state must decide to prosecute.
However, in general, any effort by Microsoft involved in filing a lawsuit is dependent upon the "damage" (basically financial) which Microsoft perceives as happening to it. If you are a private individual the probability of Microsoft taking an interest is likely less than zero. If you are a SUCCESSFUL company (where damages might be recouped in sufficiently large amounts as to cover Microsoft's costs) you might be a potential target. If you are a Government entity, then Microsoft might be very interested, but would be forced to resort to Diplomacy to resolve the issue, as, again in general, Governments are "sovereign" and under no compulsion to honor the laws of another country unless there are specific treaties to that effect which they wish to honor. ("Cross-border" disputes are incredibly tangled webs.)
