I receive a couple of quarterlies associated with membership of societies and, of course, I edit and publish a community magazine for this area. I have no intention of making that available on-line after an unscientific survey conducted by me (basically I asked some people what they thought of the idea) overwhelmingly came down on the side of "But we don't have a computer".
Other than that I cancelled my subscription to Private Eye some couple of years ago because it seemed like the only way they would ever publish a letter from me
"Sir,
I cannot disagree strongly enough with your article etc ...... I am cancelling my subscription immediately.
Yours faithfully
Snoopy"
Such letters, it seemed to me, got published so I thought I would do it as a laugh ~ they didn't publish my letter but they did cancel the subscription
~ So I thought "Sod 'em" and didn't renew it.
