Sure it can. If you're downloading it for commercial purposes (clearly the case) you're violating the license.

Legally speaking, it is extremely well established that downloading is not the type of copying that “copyright” concerns itself with. And the GPL and similar licenses are predicated on copyright laws.

Once you make the content available in some other way, then copyright law might have something to say.

People in tech used to make fun of “you wouldn’t download a car”. It’s sad that so many have reversed their principles the moment a convenient villain shows up.
