As below it all depends on who you want to entrust your privacy toI know i'm kind of drifting away for the subject, but I'm not sure internet and privacy goes together anymore. Even if you use a search engine that respect your privacy, what about your browser ? The add-ons of your browser ? Your antivirus ? The data that your OS collects and sends online ? And even if you achieve the ultimate privacy setup (Linux with tweaked settings, independent browser, open source softwares, etc...) what about your ISP ? You could always add a VPN but that seems a lot of hassle just for having Google and such not knowing your surfing habits and personal taste. And i'm not even talking about Smartphones and other IoT that collects your data like a fat cop eating donuts.
Unfortunately i think privacy online is dead. I don't like it, but it's the way it is. I just try and not to think about it, i don't have much to hide anyway. But i do miss the early days of the internet in the 90's
