Playing devil's advocate, his statement and losing the house by following his advice aren't inclusive in with each other, what he is saying is factually true.
Yoshida "It's alright not to play it everyday. Since it's just a game, you can stop forcing yourself if it's hard on you to keep that up. Rather, it'll just pile up unnecessary stress if you limit yourself into playing just that one game since there are so many other games out there. So, do come back and play it to your heart's content when the major patch kicks in, then stop it to play other games before you got burnt out, and then come back for another major patch. This will actually make me happier, and in the end, I think this is the best solution I can answer for keeping your motivation up for the game." ~ Yoshi-P.

You can easily take a break from playing FF14. You only need to log in once every 45 days(?) to keep the house, which takes all of 5ish mins. The remaining 44 days, 23 hours and 55 minutes you can spend not playing FF14 and taking a break from it. Yoshi-P says that specifically because players will always devour content infinitely faster than developers can create it, so he encourages people to not be playing FF14 24/7 since you'll eventually run out of content to digest.
His statement however, is carefully worded in such a way so that he's not saying to unsub, just to take a break, a very important distinction. People simply interpret his words to imply unsubbing is fine when that wasn't the intention behind them. They're a business; they -obviously- want you to stay subbed every month, it's simply beneficial to both the devs & the player's mental health that they don't try and force themself to play the game if they're suffering from burnout, which is what he addresses with most of his 'take a break' comments. He's not being hypocritical or going against his own words, he's just being very sly with the wording on them so that his PR response sounds very empathetic.
