Because they stand to lose a shit ton of money?

Where do they sell oat butter? I need to try that

They lobbied and won against margarine back during WW2. It couldn't even be dyed yellow, you got a little packet of yellow dye to add to your white colored margarine at home. This lasted into the mid 1960s when they just started dying the margarine like butter.

Personally growing up on a dairy farm, I'm fine with making the distinction. Like you can't label food something that it's not. You can only call Scotch whisky Scotch only if it's made in Scotland. Same with cheeses and wines in Italy and France. It's a guarantee you are getting what you paid for, the real thing. And not some fake chemical concoction. It goes even so far as soap. Did you ever notice that Dove is called a beauty bar and not soap?

Go ahead and eat all the oat butter and drink all the oat milk you want if you like it. Oats are a pretty under used crop. The majority of it ends up as horse feed. Oats are a high food value food even for humans. I enjoy making oat bread. It's quick, simple, and tasty. Along side of a chili or soup, it makes for a hearty and nutritious meal.

interesting, i replaced milk with oak milk (recently learned i'v been allergic to dairy this whole time) but had no replacement for butter

Also hot is “chaud” in French which could sound like “oat”

It only counts if you pour the oat milk super slow while maintaining unflinching eye contact with the staff.

I've seen this image years ago. I don't know how old it was already at that point.

I think this might be a meme about how the french don't like anything that goes against their national values, which heavily relies on eating "proper" food, i.e. no oak milk garbage ... but i could be wrong here.

like how they refuse to speak any language but french

Somebody with a milk allergy, or intolerance turned me on to oat milk.

For me, I like it better and it lasts longer in the fridge.

I haven't really tried cooking with it yet though.

I've been off dairy for so long that whenever I catch a whiff or taste of cow milk by oops it just seems so cheesy. Like no ty I do not want mozz in my tea lol

Ost milk

I mean, you're not helping your case here...

I think this can only come from language barrier, oat milk in french is "lait d'avoine" which doesn't sound similar at all.

In Sweden all the milk is ost milk.

Are there no lactose intolerant Europeans?

We do have the word barista in spanish.

It's not exactly the same as camarero, it's more focused on the coffee part. Same as we also have the word barman, which differs from camarero in that it normally refers to people who mix drinks and cocktails behind the bar.

I've lived in France for more than 6 years at ind point, and I can tell you that sometimes they'll just refuse to acknowledge English words.

You vastly overestimate the level of English of my compatriots. This is a 100% plausible mistake for the average English speaking French person.
Also unless it was a Starbucks or some really fancy coffee shop, we absolutely do not have oat milk as standard. And I've been to TLS, I don't recall that kind of coffee shop there.
