Intellectual & Digital Property

From Halachipedia

In very general terms, some say that if the author is selling his lectures, music, or computer program or the like, then there's a Halachic copyright. As such, it is a form of stealing to use the product without paying for it. If he is not selling it, however, or he doesn’t have any copies to sell, or you are not a potential costumer, the issue of a Halachic copyright does not apply. [1]
