The author's active on instagram (linked from their medium profile), and has more recent writing there. From that, it sounds like they don't feel as if they've regressed.

It's possible that they're not talking candidly on the shorter-form of an instagram post, but it's at least a sign that maybe it stuck, otherwise that phrasing would probably be a bit less positive.
