My proposition is to avoid making it seem that a provider is trustworthy when it isn't.

Trusting a provider because you have to use one (and not because they are actually trustworthy) doesn't seem appropriate. Either use it while knowing they're not trustworthy, or don't.

There's a lack of good options right now to my knowledge. It seems that startpage may be a viable option, although I've heard it pulls from Google's search results. Though if it doesn't have Google's trackers I would still see that as a better option.
