I am on the fence as to whether I agree with you, but I'll embellish a certain aspect: these folks keep citing how the number of DNS lookups (what pihole reports/blocks) is extraordinary, exceeding all other vendors they use, which says pretty much nothing about the nature of the payload other than that Dropbox likely has very granular client uptime data. The client could cache the DNS response instead of doing so many lookups, and some amount of rage would disappear.
