Interesting. More questions than answers, ya, but I like the way you're looking at it. It's important to try to consider all facets of it and not rush to judgment about what's the "right" way to use Steem.
I feel like I remember the name Matt Monarch from the vegan youtube scene (and IIRC he was accused of being a snake oil salesman over there too).
Funny when worlds collide.
I don't know anything about his products, but in general consider it to be woo woo when people treat health and nutrition as like a fancy pants operation that would involve formulas and special potions and whatnot. Whatever the right lifestyles and habits are... you just learn the info and adopt the habits, there isn't really a need to buy special products from someone.
It isn't the kind of thing that's innately profitable (to understand nutrition and pass that info on to people), but there are people who want to find some angle to make a buck off of it.
It's funny tho that there isn't really a great specific reason to downvote him (is selling snake oil bad only when it gets into trending? or it's always bad? lol), but somehow it seems right.
lol I dunno.
I think that's just always the risk you take when you use bidbots, that people don't necessarily need a good reason to downvote. And if it gets into trending, they may have higher standards of what's okay.
