Switzerland has just 8 million people, which are divided into two big language groups. And most people speak (or at least understand) English. So, it's natural for the algorithm to converge to content in English.

This is wrong. In cities where there's a lot of tourism, they might understand. Most Swiss people only speak their local languages (German or French). As for those living in Ticino, they tend to be better polyglots.
This is simply not true. Even standard German is a second language in Switzerland. I’m Swiss.
Lived in Switzerland and this is really not true.
What I've learned is that since Switzerland has 3 official languages (German, French and Italian) children and teens at school focus on learning one of the other two regions they are not from.
In particular this leads to French and Italian cantons to be moderately fluent in each other's language. Strikingly when I lived in Lausanne, more people knew Italian than English. English was really not on their radar (plus, add that francophones are kind of elitist when it comes to languages and don't really like to consume content that is not in french).
In German speaking Switzerland proficiency in English was still subpar from most of the rest of Europe when walking in a shop or going to a restaurant.
