You are confusing branding with product description. Thunderbird can call itself 'a better programme' but not 'a better outlook'.

There is also no "meat envy". But you might like a dish called 'chicken tikka' and no longer eat chicken. Or you might be a meat eater unfamiliar with vegan products but want to cook for your son-in-law something similar as to what you cook for the rest of the family. Why should you not be able to buy a product called 'fake chicken' to be use as an alternative ingredient.

As long as the advertisement is not misreading (claiming in big letters 'chicken fingers' but actually in small script adding 'not made of chicken') there is literally no reason to prohibit such convenience labeling and naming schemes.
