For copyright infringement, they'd need to actually redistribute the code.

IANAL, but I don't think so. In MAI v. Peak[1], the court determined that even loading a program from disk to RAM was a copy, and therefore infringing without a license. Congress has since then added a specific exception for "Machine maintenance and repair", but that's it. Copying from a remote machine and storing it in their disks should certainly qualify.
