Z:gnu-www-ja-ucita--a81df3-UCITA does not apply only to s/en

UCITA does not apply only to software. It applies to any sort of computer-readable information. Even if you use only free software, you are likely to read articles on your computer, and access data bases. UCITA will allow the publishers to impose the most outrageous restrictions on you. They could change the license retroactively at any time, and force you to delete the material if you don't accept the change. They could even prohibit you from describing what you see as flaws in the material.
