I don’t think your question is so much about the keycaps - plenty of keycap sets are available that include Mac keys. Your question should be which keyboards are compatible with MacOS, because not all are.
For example, I built a Feker Alice but even though it’s advertised as Mac compatible, the software was for Windows, it didn’t connect correctly and I ended up having to flash it on a Windows PC I was able to borrow. It works now but I’ve been unable to customise the keys as I’d intended, and I’ve learnt my lesson about checking Mac compatibility.
Maybe stop eating shampoo then. (= They partly own L’Oréal, and by extension all the L’Oréal brands: Garnier, Maybelline, Vichy, Biotherm, etc.)
To your actual point though: A) that depends on which country you live in, given that their products are manufactured differently in each country/region. B) it does also depend on what brand you’re referring to. I find it highly unlikely you dislike EVERYTHING in the Nestle machine. Hot Pockets? Perrier water? Nerds? Smarties??
