What I am saying is that just because a company says it works by certain rules it doesn't mean that's always true.

Companies break the law, they break their word, because it's run by humans and it's there to make money.
Also a quick google says that privacy policies aren't legally binding
http://ir.lawnet.fordham.edu/iplj/vol27/iss1/5/ although some state they are inside the policy.
True, but that's a straw man argument, I never said that google alternatives are more trustworthy. What I have said is at least they aren't
definitely using one's data in ways that benefit the company at the expense of the individual, as google does.
That's an American site, I can't work out if privacy policies are binding here.
You've got to be aware that websites you visit probably use Google Analytics, the use of cookies, your phone tracking where you are, unfortunately, it's part of modern life. That doesn't mean that it's always acceptable or desired but it's going to happen whether you want it to or not. The only way no to be profiled online is to stay offline.
Again, straw man. If there's something one disagrees with (e.g. surveillance) it's better to reduce one's exposure to it than just put up with the status quo, no? E.g. if I don't want to be tracked I should reduce my tracking exposure, not accept it.
(Indeed I do make efforts against all those things you mentioned. Google Analytics blocked by uBlock Origin, regular deletion of cookies (and cookies off on the phone), phone location always off unless using sat nav, google location history switched off... It doesn't have to be a part of modern life.)
Are you saying they already don't or can't listen in? NSA has been analysing communications for decades, and I would imagine GCHQ and other intelligence agencies already do. The companies that run services will have the ability to intercept as well.
No, just an illustration. I think people think of emails as being less sensitive than other personal data for some reason.
Also I think you're mistaken, don't/didn't the NSA and GCHQ record metadata, not actual calls? Maybe the new law changes this.
That's the best you can do but I wouldn't trust anyone 100%, from the largest to the smallest companies, there's always a risk. Even if it's not them spying there is also the issue of security and someone else getting your data.
True enough, but again it's always better to use more trustworthy companies than less. With google you're certain to be the product.
