This may be a controversial post because it strays from the exploitation of non-human animals, but this is a story about human bodies being sold and used without their prior consent, which to me speaks to a similar (albeit more severe) indignity that non-human animals face in the medical industry. That is to say “this isn’t vegan”. Feel free to downvote this post heavily and say as much in the comments if you feel this isn’t on-topic for this community, as I know there are plenty of other places that will address this with an appropriate level of appallment.
This is the definition I always use concerning veganism. As soon as we get a benefit from something, we become biased. We lie to ourselves. Every vegan here can remember a whole lifetime of lying to ourselves. If someone still trusts themself to distinguish which forms of exploitation are “beneficial” to the animal being exploited, they haven’t learned a damn thing yet.
