> Opera, or Google the search engine? If it's Opera, Chrome then is no better (and arguably Gmail holds the keys to your kingdom anyway)
True, if I used Google, or their products.
But, I use Mozilla, who are publicly auditable, and an email provider that is not located in the US.
The majority of visits to websites have no search engine interaction, but those that do, make use of DuckDuckGo and the like.
> More generally, I don't see how China having your browsing history is worse than the US having your browsing history and your authentication attempts and all your contacts and just everything, completely everything.
Bringing up the US here, isn't entirely relevant. We're speaking about China, who have demonstrated some interesting ethics around people who are non-Chinese over the past few decades. Yes, the US is of concern, but that doesn't mean that China isn't one.
Secondly, your browser doesn't just have your history. It also has your authentication attempts, because it makes them. It also controls what certificates you use, and can trivially be used to MITM every authentication you make, unless pinning or other not-well-adopted practices are used. Which can give them everything.
