I do mean MITM in a generic sense. Regarding the Third Party Doctrine, the fewer third parties with access to the information, the more sovereign over the data the remaining parties are. But I agree with you that ISPs and mobile carriers are other companies who intercept, profile, sell and partner away plaintext information - and indeed in the case of at least some mobile carriers encrypted communications too. I agree with the assessment that this is an opt in feature. I have spoken about the reasons I won't be opting in. (In my opinion it is a very bad trade.) Definitely agreed that many other parties have access to the data. I disagree that this is an argument to add another. [By the way, thank you very much for taking the time to speak on HN about Flywheel from your position. :)]
