Because running software involves making copies of that software. This requires you to have permission from the copyright holder. The GPL provides you with that permission, without adding any further conditions if the copies are just for the purpose of running the software. http://www.digital-law-online.info/lpdi1.0/treatise20.html http://www.digital-law-online.info/lpdi1.0/treatise20.html It is now well-accepted that copyright protects computer programs and other digital information, whether they are in readable source code form or are an executable program that is intended to be understood only by a computer. Copies are made whenever the program is transferred from floppy disk to hard disk or is read into the computer’s memory for execution, and those copies will infringe the copyright of the computer program if they are not permitted by the copyright owner or by copyright law.

1. Even if that's the current legal theory it's bullshit, and I can run code without having copies in ram if I need to. 2. 'if they are permitted by copyright law' Fair Use is part of copyright law, has that specific defense been challenged when it comes to software execution and caches in RAM?

  Regarding 1, I really don't believe you can run code without copies, or copies of a derivitave work, being made in the process. That said, I can't read a book without reflections in my eyes...

    I could run it directly out of a ramdisk, or maybe transfer it to an embedded processor that can run it directly off the flash chip without even a processor cache. There's a whole variety of ridiculous things I could do to avoid the ridiculous restriction. In practice I would trust fair use and try to use such as a defense if sued.
