Yeah, the only way you can anonymize this data is if you decouple all the data points from any way of re-associating them, and then take care of the timestamps

Yeah, the only way you can anonymize this data is if you decouple all the data points from any way of re-associating them, and then take care of the timestamps too so you can't just find sequences that way. If someone's really clever they might even have good ways to get past that, but I have enough second-hand familiarity with some of the players in this space to know they're aware of at least those methods. Whether or not they DO it consistently... well, I'm not holding my breath.
