You keep saying that, but I think that maybe you could make a better effort to understand other people’s analogies, even when they don’t map neatly to the mental model you have in mind.
My point is that a prevention mechanism can have utility for those employing it, even if it’s trivially circumvented by those who really want to. It does not have to be a binary thing, where either it works perfectly 100% of the time or it’s useless. It’s obvious to me that this feature could have a stifling effect on spread of content, and that might be well enough to have fulfilled its purpose.
Mind you, ideologically I do not necessarily agree with it, but that’s another matter.
