I could tell who this comic artist was, and what the change was ey made, but I won't – it's irrelevant to this essay. What I'm interested in is the idea that one can publish a work on the web and then change it after it's already been viewed.
The idea of revising already-published works, and of retracting what has already been publicly said, is not new, or even controversial. A 'corrections' box in the newspaper is standard practice, poems published more than once are often altered to some degree between printings, and essays and editorials are occasionally followed by literal retractions. The Gettysburg Address underwent multiple revisions even after it was delivered; the version in the textbooks is a modification of the one Lincoln delivered on the battlefield. What makes the online case unusual is that the work is only published in a single place, and it is often easy for the artist to unpublish the old version, leaving only the altered piece with no evidence of tampering.
This secret (or semi-secret) rewriting angers me. It is sometimes hard to make a case for what harm the creator of a work does in revising or removing it from a webpage; while in specific cases additional factors may apply, in general the harm it does lies only in the loss of the original work, either to deletion or revision. However, further harm can lie in the corruption of responses to the original work, especially when it is deleted altogether; when element of a discussion is removed, it eliminates the capacity for the audience to judge any part of the discussion that involves that element.
Even if the alteration of a online work is announced and explained, there remains some value in the original version which is lost if the revision is the only version that can be viewed. Admittedly, while this chain of reasoning can lead to extremes – like requiring that all first drafts be posted, and posted before the actual work, when possible – it is not unreasonable to be interested in the version which was associated with the initial release, and mere information on the differences does not suffice in this regard.
I think Eric Burns of Websnark had the right idea when he stated his policy on mistakes on Websnark (original statement heavily mangled to remove context):
[...] So, I thought I'd type for a few minutes on one of my unwritten policies for Websnark.This is an attitude I admire. I admire it partly because it shows bravery and honesty, but I also admire it because it means that (for example) when he writes an eloquent rant that later turns out to be unjustified, the rant stays available for reading anyway. It means that points he made in the rant are still available for consideration. And just because the central thesis gets refuted doesn't mean that all the ancillary points become invalid.If I make a mistake, or blow something, or post something I later regret... I'll own up to it, but I won't delete it. This is a record of... well, something, at least. Of my thoughts and blatherings, if nothing else. And when I blow it, I'm going to leave it up and own up to it.
[...]
We live in an age where the historical record is easy to alter. We combat that not with technology, but with integrity. When I overreact or blow a call, that mistake becomes a part of this archive. That just seems fair to everyone.
I admit that, under many circumstances, the original work is almost irrelevant. Furthermore, under some circumstances, change is almost demanded, as in the case of the misplaced rant, and the case of the duplicated punchline. I admit that sometimes changes are almost unambiguously improvements, and that the value that was in the original is sometimes entirely subsumed in the revision. But even in this case, the best case, a certain amount of history is destroyed by the vanishment of the original version.
And that's probably what bothers me about it. Knowledge gets destroyed, however useless that knowledge was, and in a world where nothing is perfect, we need all the knowledge we can get.

As for what is permissible – yes, the domain owner (or, in my case, tenant) should have most of the control. However, besides the deletion of trade secrets and other weren't-the-poster's secrets, I'd let most stuff pass, just with comment. This is partially because LJ doesn't allow comment editing.
(So, would you mind not using those <blink> tags? They're annoying, but not enough to justify deleting!)
