Hey, Arnaud here who develops Kiwi Browser. Thanks for quoting the GitHub answer.
Yes, when you are one of the smaller browser, you don't get the direct link to [Bing.com](https://Bing.com) or [Yahoo.com](https://Yahoo.com) and the special referral code but you have to use the same setup as browser "extensions".
Extensions are forced to use intermediate redirects. This is why you see "fastsearch", "mysearch", etc, with browser extensions.
When you have a small browser (like Kiwi Browser, but Kiwi is not that small; it has about 1.2 million daily active users according to Google Play Store), you get in this shit-tier "untrusted third-party browser extensions partnership" and this lousy setup.
It's not a conspiracy, if I could put the [bing.com/?source=kiwi](https://bing.com/?source=kiwi) I would do it 100%.
You can even know that for one simple fact; most of the users (how many, I don't know because there are no analytics

) use Google Search, and Google is a plain old-school direct link pointing to [Google.com](https://Google.com)
What if to add an option in the Search settings page to add an additional option to go directly to Bing / Yahoo and to explicit that the other (current) settings helps to monetize/fund the browser ?
Wouldn't that make everyone happy ?
