You can't "lock" something that doesn't exist.

1) No, it is not. The entire point of the post is the use of the ENGLISH WORD "genderlock" (and how the OP thinks it's being misused). The OP makes an ENGLISH semantics argument. Therefore, it's impossible that Yoshida could have "used genderlock wrong" because he would never use the word genderlock.

2) I would have to look at the Japanese actually used to confirm, but I guarantee it wasn't a single word he used. Likely he said something like, "I wasn't happy that Miqote and Roegadyn were missing genders". There's no word in Japanese for "genderlock".

3) Yes, I'm fluent in Japanese. At the very least I know that there is not a word in Japanese for "genderlock".

Just look at the Japanese thread regarding that. You'll see they almost use this word 性別固定 all the time, which roughly means gender fixed, not locked (thanks google). They only used the term gender lock (in Katakana) when talking about how the west describe it.

技術的に難しいからやらない、ではなくて、難しいから目をつむって可能な範囲で実現する、というのがFF14だと思ってます。服の突き抜けとか。
NAフォーラムの方ではジェンダーロックだとかなり紛糾してますけど、だったらやらないよりは今回のような形でもやってもらえた方がうれしいです。

拙い言葉になりますが
海外の方がいわれているような所謂ジェンダーロックというものに関しては私はあまり気になりません
どちらかといえば私は「女性はセクシー、男性は筋肉質」といった古い固定観念にがっかりしています

And I doubt Yoshi P used the term ジェンダーロック in his interviews at all.
