Ecosia, a search engine that dedicates its profits to tree planting, has announced that it will never sell the company, emphasizing its non-profit model. However, there are mixed opinions among users regarding its financial transparency and the effectiveness of its environmental claims. Users have raised concerns about the salaries of executives, the legitimacy of tree planting claims, and how Ecosia compares to other search engines like DuckDuckGo and Qwant. Some users are intrigued by Ecosia's business practices as a Steward Owned company and are seeking more information about its impact and operational structure. There is skepticism about potential greenwashing marketing tactics, especially after the introduction of an AI chat feature, with questions regarding independent verification of their tree planting efforts.
