Hi - I'm a person from Startpage. I'll share your feedback with the team, but here I can respond to some of these things.

JS: Startpage does use Javascript, but only to enhance user interaction with our site and improve the search results we provide.

ADs: Startpage displays at most 3 ads. Like other private search engines, Startpage's revenue model is based on contextual ads.

Let me know if you have questions or suggestions.
