"Cultivated meat isn't vegan, because it comes from animals."
They create demands veganism does not make and push away people who might join, without helping a single animal.
Why it is weak
The definitional objection confuses the letter of the commitment with its spirit: veganism is not a closed list of forbidden ingredients, it is a commitment to ending unnecessary harm to sentient beings.
The "it's lab food" variant is the naturalness fallacy. There is nothing more natural about an industrial dairy cow than about a protein grown in a bioreactor. The relevant difference is which process causes more suffering.
Rejecting the technology because it feels like a symbolic surrender sacrifices the result for a purity that benefits no real animal.
How to say it better
There's a real risk that the technology becomes a badge of "conscience" without replacing animal farming. That justifies vigilance, not outright rejection.
