I’m not aware there is such a list. Logically it’s mostly small countries where they speak their own languages where no big corporations that produce ads have any interest in. You probably will find some comment like mine where they mention certain countries but this can always change any day. Sometime there is a single advetiser in a country but even then you will see their ad much less frequently than the common US/English based ads.
I can recommend you the Nord Vpn Firefox addon which allows you to only use vpn for certain domains which would be anything with *.twitch.tv
What a headline. It literally fell 3%… That’s not much. Actually still higher than their April value. They dropped more than 50% in the beginning of the pandemic and have not recovered from that. Whereas Airbus easily pushed higher than pre pandemic level. So yeah not looking good since a long time.
