I know several corporations that actively violate the GPL license of "poor" people's projects that have no money or desire to litigate, so they get away with it.
Companies pirating GPL software should be aware that no matter how small the developer they are opening themselves to a slamdunk court case.
It's not a slam-dunk case if you can't afford or aren't interested to litigate in the first place, which is many of such projects.
