The hologram bracelet and other similar 'products' are unethical.
As for this article and OnlyFans. I don't see a problem with selling nudes (although some people might), but what I gives me pause is the analysis that the 'fans' think they're buying intimacy and friendship. If that is the case, this is highly unethical unless you actually provide some sort of a real human relationship (which of course would not scale very well).
For example I find Loot Boxes to be a highly predatory and unethical way of monetization in gaming yet they are legal, I also find it completely ethical for a person to grow a certain plant in their home garden but it is illegal...
yes, in some sense. when they differ, i would choose to make (or lobby for) what is unethical also illegal.
dislike is very different from unethical.
Dislike is my taste - other people could have different tastes.
Unethical is defined by me as actions that "if everybody did it, society would collapse".
such as?
If you exclude illegal acts, i cannot think of what unethical, but high demand goods/services there are that are currently under-served. Gambling, prostitution and other such vices? All highly competitive.
