You’ve seen this done before, right? A small business or company sees something online that they really like, it fits in with their brand image and audience, and they think, “I can totally use that!” So, they grab a screenshot, download it, change a couple of things like taking the logo off the original image and then put theirs on, and voilà! Share it.
Guess what? That’s theft. They’ve stolen the work of someone else and passed it off as their own. Intellectual property theft is theft.
