> Since Abrowser is configured to execute all JavaScript by default, Ebay, Amazon, and even DuckDuckGo execute proprietary JavaScript when used in Abrowser. By suggesting these search engines, Abrowser guides the user toward proprietary JavaScript. I think that if Abrowser is not going to block non-free JS by default as Icecat does, it should not go out of it's way to direct users to pages that have non-free JS.
Indeed. Pointing to a proprietary addon or to poprietary javascript on a search engine is equally bad freedom wise. No difference at all. And if we think we shall exclude the first we shall by the same logic exclude the second.
