This is a weird criticism. No person can guarantee that some other person in the future will or will not do something.
Pointing out that the company will revolve is not a criticism.
I do think it's kinda funny they are trying to oust your ISP and insert themselves, as the keeper of traffic logs. Either way, I guess we're going to choose a big corporation to trust.
Lastly, I don't think your point stands, when the quote says "we won't sell your data, EVER" (my emphasis)
It's a weak promise and a valid criticism.
