Interesting. I recently saw the movie "Dallas buyers club" that shows the struggle of a man against FDA. This is not a masterpiece but worth to see it.
Also, one year ago i quited cigarette, and it really changed my life, even if I'm not cured yet. Researchs recently prooved that the use (or not) of tobbaco got impact on the microbiome. That's why people who quit are often getting fat.
Moreover some studys linked anti TNF to weight gain, I would not be estonished if it was once again related to bacterias.
So there are many ways to influence the microbiota's composition.
FMT is one of them, but it's still experimental (and that's a shame because it was invented many years ago.). Personally I don't feel sick enought to do it, I mean, I prefere to wait a few years because medicine will probably improve a lot. But, I believe it is a duty to spread this information because many people are suffering without even knowing what is the microbiota, like I use to do only 6 months ago. And, many websites- in France at least, probably paid by the industry - are not in a hurry to share the news.
