I take it one more step: if you step across any of my personal lines, I will stop doing business with you where feasible.

For example:

- I unsubscribe from your mailing list. But you have another, slightly different one, so I must unsubscribe from each - >1 click to unsubscribe - physically mail me more than about 4 times a year: your product probably sucks - make it difficult to cancel my account or subscription - and many more

At this point I may end up living in the woods with no internet, but that sounds delightful!
