For now, Sony appears to tolerate these preservation repositories, focusing enforcement on modern console exploits. However, this stance could change, especially given ongoing antitrust cases that challenge how large companies control closed digital ecosystems.
If your intent is to "look into" the contents of a .pkg file before installing it, you should use specialized PC utilities rather than a standard text editor:
If you have a PS3 on OFW, you can download a free theme or demo from PSN — those are PKGs. Transfer them to a PC, open one in a hex editor, and spot the “PKG” magic bytes at offset 0x00.
