US here, I can't see it either. I noticed the tweet mentions European Data Protection Supervisor (EDPS), is this EU only?

My company is in the US. I just checked and found that we have the setting in our admin console and it was on by default. We do have a paid business account.

Try going to your account then from the menu go to Settings > Third-party AI

Heres what the link looks like for me in the US: https://www.dropbox.com/account/ai

Paid subscribers can see it in US, not sure whether it depends on the subscription tier though.

Im in the Netherlands and also dont see the setting. Using a basic (free) account.

I don't have it (from EU), so this may be limited to a subset of users, but in any case I believe that it would have to be opt-in for EU users.

I'm in the US on a paid account and I had it.

In Canada, I also couldn't find this setting.

I'm in Canada and I had it. I'm on a paid account.

I stopped paying a long time ago before actually deleting my account today. So maybe the setting was implicitly turned on for non-paying customers. Wouldn't surprise me.

In the US, not seeing this either. I do have a free account though, not sure if that makes a difference.

Not in Turkey either.
