Interesting solution to let the user pick which search engine to use. Sadly Bing is shutting down their API, it would have been great to be able to use that as well.

Interesting, does DDG have plans to switch or start their own index?
There are some provisions for their larger customers, see https://www.wired.com/story/bing-microsoft-api-support-endin... (https://archive.ph/IVKGT). So no DuckDuckGo and Ecosia won't lose their Bing backends.
