I think this is wrong. It's not free for Google or Apple to log data from their app stores/call logs. It costs massive amounts of storage, it costs training for employees on dealing with personal information, it costs engineering time and money to run the systems. It's absurd to say that it's cheaper for these companies to do this than not do it. They're making a decision to do it because it helps them make money (directly through monetizing the data or indirectly through running another service). I get where the author is coming from, I agree that privacy is important, but the thesis is wrong(for these examples, idk about the telcos one)
