Hi - Startpage person here. Maybe I can clear some stuff up.
1) Startpage provides Google results, but Google never sees you. Startpage submits your query to Google anonymously, then returns Google results to you privately. For more info on we keep your search private: https://www.startpage.com/blog/privacy-awareness/how-does-st....
2) Startpage is HQ'ed in the Netherlands, meaning we don't have to comply with US government or law enforcement and comply with EU/Dutch privacy laws such as GDPR. Also, we’re not likely to receive requests by governments to hand over user data – simply because we don’t have any.
3) In 2019, Startpage announced an investment in Startpage by System1 through Privacy One Group, a wholly-owned subsidiary of System1. With this investment, the plan is to further expand privacy features and reach new users. (Lots of new privacy features in the works!) The Startpage founders have control over the privacy components of Startpage. And! After conversations with the privacy community, Startpage was recently relisted in PrivacyToolsIO. More info on that: https://support.startpage.com/index.php?/Knowledgebase/Artic...
They might claim privacy, but de-googlers forget that Google is a much bigger target for law enforcement than any of its alternatives.
If you don't trust Google to not collect your data, in spite of turning that behavior off in your profile, why would you trust Startpage?
