There's a lot of hate here, and probably justifiably so, but this is actually (worded slightly differently) a core of Buddhism. The belief that our attachment to things is what actually causes misery is relatively fundamental, even if that attachment is to things like food or health. There's a lot more nuance to it than that, but it's the gist of it.

I can totally see how from an outsiders perspective this is 100% a "thanks I'm cured" moment.
