There is a thing called the
BSA who performs "raids" or audits at companies to check if you've got your licenses right. If not, you get a settling proposal, a limited time (1 month iirc) to get it fixed. After that, they can start a civil case.
In many countries copying software is not allowed by law, but not enforced. It is the same category that pirated multimedia is in.
Going after an individual would have little gain. I think most individuals settle, if they're not pirating 4 or 5 digit price software.
If they are using 5 digit price software illegally, and it comes to court, the software company has to prove loss.
For example, a student using pirated Altium did not gain from it (he's not a business) other that he/she learned how to use Altium. There would be no significant loss if you ask me.
Sometimes, in some countries, such case is often used to set an example. By claiming several million dollars worth of damage.
They know a student or hobbyist is unable to afford this, they won't gain anything except publicity. Positive or Negative depending on which side of the
FOSS line you're on.
Question for the mods: why are newlines allowed in the topictitle?
