Something to note is in the earlier years of computing software being copy written was not really a thing. The big thing was software for getting a specific piece of hardware to work. Most people were just concerned with getting things working, so when people came along with software they wanted you to pay for it was not really normal. Making the software something you paid for was a change, and so making it difficult to copy or distribute the software was not incentivised.

I expect the first breach of license was probably not because of intentional piracy, rather it was probably just a mistake or misunderstanding.
