It's official Parsers are illegal in FFXIV

[Tupsi]

Isn't the key phrase here "would not normally be able to do in game"? Can't a player get his DPS (although using a lot of math) from the battle log? Since that is an action a player could normally do in game, isn't that quote saying that it is, in fact, okay?

Either way, I don't care. I don't use them. /shrug

No - Parsers read into data much more than you can "eyeball", hence why they're a 3rd party tool. They also display DoT damage which you, as a player, can't get an accurate number by eyeballing unless you have the cleanest battle log known to man.

It was either 2006 or 2008 (can't remember which year, if not both) I knew several people who were banned for using windower in XI

Yep, SE bans for it if you're dumb about it, Windower itself they don't care about (it is a 3rd party though) but it's the cheat like plugins that people adamantly defend and will only list say, the one that shows you TP and MP of players, but not the stuff that, you know, lets you see through walls...or run through them..or have exact readouts on monster pop times and so on.
