A lot of people I know set the language in their phones to something else.

It could be a language that you're either learning or you're trying not to lose.

A friend of mine who speaks a few languages set it to Greek because out of the five or six languages she speaks, Greek is the one she's struggling with the most, but also the one she cares about the most.

Another friend set it to Welsh. That's because he's Welsh but most people in Wales speak no Welsh at all, and the language is dying, and so he keeps his phone to Welsh because he doesn't want to lose it.

I use English. And I use it for everything, from my phone to my email and my YouTube.

Except, for whatever reason, I woke up this morning and opened YouTube and all of a sudden the language had changed to my native tongue.

Why? I didn't ask it to do that.

I'm assuming it detected I'm now in my homeland, and so it decided to change it. Cool. I'm going to Dubai later last year, should I expect YouTube to switch to Arabic while I'm there?

I had a similar issue with a crypto app.

I got an email. It read, "hi, we detected a lot of traffic from country XYZ, please provide proof of address since you switched addresses"

That's a problem. Because I did not change addresses.

Tech firms need to stop assuming, and they need to stop making changes based on unverified assumptions. If I want my YouTube channel language switched to Klingon, YouTube'll know. Because I'll do it myself.

P.S. - I didn't like the thing with the crypto app at all. They asked me to provide proof of address in a country I have no address in. That's a red flag. I can't prove a negative. No one can. So I emptied the app, deleted it, and now they fcuk off.
