It's a fact of online life that our profile is somewhere. Each time you connect to the web the browsing data and e-mail must be passed from one service provider to another. That's the way it works. There are two aspects to this that are changing the ad-hoc way it was done in the past.
Security: I don't object to it from a security point of view, however, I do object to it without the proper safeguards in place.
Commercial: I do object to security monitoring by commercial businesses as I don't believe the safeguards are going to be in place. If it's just commercial data for relatively simple IBAs there should be opt-ins and opt-outs.
The only true way to avoid all this is to disconnect and go offline. Even so, that is harder than you think because certain data has been transported to the Net as part of public databases, such as phone numbers, electoral role records, etc. There are some opt-outs, but you need to look hard for the option.
