It doesn't matter for English website because you usually send out emails with "Hi Joe".

Once you internationalize you will need this because in German it's an absolute no go to address a stranger by their first name (at least for B2B services).

And internationalization is on the road map for a lot of companies.

They'll survive being addressed by their name. Much better than systematic sexism.

Devil's advocate: They'll also "survive" being "misgendered." Maybe embarrassing/rude event, to be avoided if possible, but not everything has to be "systemic -ism."

You may wanna read up on honorifics [0]. That stuff is cultural and you'll be persevered as unprofessional or even non-trustworthy by failing to properly use it.

Not allowing women to work is also cultural. Doesn't mean it's something we should support.

Huh I didn’t know that! So does it mean that websites internationalize even the salutations? Do they replace “Hi Joe” with “Good day Mr. Brown” in Germany?

It depends. If it started in an english speaking country, then more than likely not for a long time. If it started in a germanic one, it'd almost 100% be the last name.

It has less to do with where it started and more with the language and what field the business is operating in.

I was working for a UK steel supplier and they would address all their email recipients with their first name. We had to change this when internationalizing into German. If you want to sell to Germans you are much safer to use a more formal tone.

Slightly related to that is the formal and informal you that exists in a lot of languages.

I was also working for a German fashion startup mostly targeted at young women. In German it was fine to address everyone by first name and the informal you, but when translated the page to French, we could keep the first name but had to change the informal you to the formal one.

Many of the examples on that website are not from English-speaking countries. "diverse" and "female doctor" are typically German, and "male" = "bad" was likely mistranslated from Italian (or another Latin language)
