Ultimately, as an MMO, this game is "public domain". Whatever you do within, your numbers, your chat...all of it is "public" to a greater or lesser degree. Square Enix itself shows a surprising lot of information about players through lodestone.

As such, consent for sharing public information is not really required. That applies both in real world and in this, and there are very few limitations on what information is excluded (largely offensive or intimate one) from this freedom.

Parsers and the corresponding logs thusly are in no way restricted by regulations of any sort (whether or not that is "proper" is another thing entirely). It's just a matter of Square Enix not wanting to take chances on the possibility of them affecting the community negatively, while still requiring time and money to develop.
