Sure, that’s what I thought. And Ecosia doesn’t do the same?

I do have an opinion about Ecosia, but it’s just based on feelings, so it doesn’t even make sense to share it. Apologies for not answering your question.

Instead I would like to focus on this point:

Ecosia isn’t very private, since it sends data to Bing

Also DuckDuckGo does this, but they aggregate and anonymize that data before forwarding it to Bing. That’s probably the best they can do without building their own first-party infrastructure. I would imagine Ecosia does the same.
