Rabbis aren’t popes. They don’t get to decide what is or is not offensive to Jews in general. Sure, very religious Jews might have a problem with it. And I could not care less what they think. Especially when they’re the minority in the U.S.
62% of self-described American Jews say being Jewish is mainly a matter of ancestry and culture, while just 15% say it is mainly a matter of religion. Even among Jews by religion, 55% say being Jewish is mainly a matter of ancestry and culture, while 66% say it is not necessary to believe in God to be Jewish.[3]

Do you honestly think most Jews would have a big problem with my wife saying a blessing over the menorah when most of them don’t even think you have to believe in a god? I guarantee you more Jews were offended by Bradley Cooper playing Leonard Bernstein with a prosthetic nose than they would be over a non-Jew saying a Hebrew prayer.
Rabbi’s aren’t Pope’s and they’re born to argue so when the vast majority of them clearly state that a non Jew saying Jewish prayers is contrary to the principles of the religion then I’m going to accept that as a religious decree.
So yea your non jewish wife saying the bracha is a problem. You’re welcome to practice as you see fit, no one’s going to pull your Jew card over it but that doesn’t make it halacha/Kosher/ cool or any other version of acceptable.
Why do Rabbis get to declare what is cultural appropriation when only 15% of American Jews say Judaism is about religion?
It sounds like you are offended by it. I would love some evidence that the general Jewish population agrees with you.
Why do the people who devote their lives to studying the scriptures of the religion get to be the ones who decide what’s acceptable within the religion and what’s not?
Because they’re literally the subject matter experts. It’s also pretty damn clear in the tanach too. In order to perform the mitzvah you need to be Jewish.
I’m not offended by how you choose to practice your religion, I’m pointing out that what you’re doing is absolutely cultural appropriation and off sides with the understood practice of the religion as a whole. You’re the one who seems to be offended by being called out on this, and that’s for you to come to grips with not me.
