What would solve the "always logged in" problem is if I can enter a 6-digit PIN to use the service on a random computer or VM I also can't associate searches I do for work with a personal account, and installing special software (this privacy pass client) is also iffy, so that's not going to work for people like me Otherwise I'll have to use a publicly accessible search engine all the time anyway, since there's no way I can get my boss to pay for a search engine when I can't even get him to pay for our primary communications mechanism (calls and chat) that is hosted by a third party relying on donations
