Not entirely true. Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals.

Which leaves certain gray areas regarding the consumption of sentient beings. For instance, eating roadkill does not cause suffering for animals. Similarly, when Inuit people hunt animals, although it may cause suffering, it is their only means of survival. There are also instances where the only available medication contains animal products. Additionally, killing a human or non-human animal in self-defense when you haven’t intentionally put yourself in that situation would be vegan.

On the other hand, the consumption of non-sentient items does not have to be vegan. For example, milk, eggs, and honey cause suffering for the animals that produce them.

Regarding the consumption of a CEO, one could argue that killing is a form of self-defense and that eating them doesn’t increase their suffering. Along with the net positives effects on the world, it could be considered very vegan.
