"You are in a dark forest. A disembodied voice speaks to you. They want you to follow."
How many voices? Would it have been more correct to say "They wants you to follow"? Should you contort the sentence to drop agency, saying "You should follow"? Is the pronoun referring to some group of people not included in this paragraph?
s/They want/Ze wants/ solves all of these questions immediately and simply.
In most cases, it comes down to stylistic preference. Some people like to use "it". Some people like to alternate "he" and "she". My preference is ze/zir/zirself. Some people feel threatened by it, as if someone else coding in a new language means their old standby of C90 is not good enough.

Hardly 'simply', as it prompted the GGGP to go and Google the term. You're changing some very significant terms in the language, and it's only simple if everybody is on board with the change.
It's bad grammar. 'He/she' is singular, 'they' is plural. On the other hand, I consider it a significantly lesser transgression than just introducing new words (with poor aesthetics, IMO).
No, it's not. It was made-up in the 1740s, and has never really been followed as a rule that closely.[1]
Or from Geoff Pullum[2]:
>"Avoid singular they if you want to; nobody is making you use it. But don't ever think that it is new (it goes back to early English centuries ago), or that it is illogical (there is no logical conflict between being syntactically singular and semantically plural), or that it is ungrammatical (it is used by the finest writers who ever used English, writers who uncontroversially knew what they were doing)."
