Oh sure, you are right. But the thing with collecting heaps of data is that it needs to be harder. If my ISP is going to filter and process all packets in realtime, sure they can get a lot of unencrypted stuff from me. In essence, other than heavy censoring countries like China, I don't think most ISPs do that (a number of users doing that is pretty small, so the effort on their part is not worth it).

And as you and others have said, it can be done by looking at IP addresses i connect to as well.

What I do achieve is that nobody has a "full" picture of me, but only some subset of data that I transmit.

I also use two independent ISPs in a loadbalancing/failover configuration, so that helps with the cause as well, thougb my primary use is fail-over since I am in this internet business :)
