I'm curious if they have data about how much compression they are achieving? Most HTTPS servers are set up by people who use quite a bit of compression in the payload (gzip of web pages, etc, "minification" of javascript), so I would hypothesize that the actual savings are minimal on the average.
However, it points out that there is a man-in-the-middle problem with HTTPS alone. Your phone's browser should be checking the certificates more rigorously than it does. It can do that quite easily, and I think the destination can do that in Javascript that comes with the pages.
"We don't look" is not a defense in the EU privacy regime, and probably not in the US one (though many US Senators think that ISP's looking at content is just fine).
