Interesting how the landscape and conversation has shifted. Sadly, it doesn't appear possible to even have a definition of publishing that both maintains the right of the public to access information, and allows for individual privacy.
Options like disabling crawling are insufficient, essentially web servers have to read author's minds to divine their intent in order to not screw up. Don't crawl certain kinds of content and you might be accused of discrimination, providing services to one group and not others.
Ownership is a weird thing.
Yes, but under current copyright laws they are not allowed to distribute them without your consent.
In practice, the nature of the web allows everyone to keep copies of everything if they want. But if someone republishes it, then you need to use the DMCA process (for American websites) to take that content down if it violates copyright.
Going back to print, what if you print something you don't want out there anymore? Well if people have already bought your book or magazine, they have bought a right to that physical copy. They can even sell the book or magazine to anyone else (granted that the content isn't illegal).
It's not because they say it exists that it makes it valid in practice.
Says who?
On the internet, everything is as fresh as this morning, forever. No longer do we have "do you remember when so-and-so used to say that stupid stuff, boy have they changed!" Now it's "look, here's a link to so-and-so staying stupid stuff, now we know what they really think!"
The idea that once something is in the public it should remain there firmly embedded, forever, makes sense on the surface, but definitely seems to break down when examined closely, in my opinion.
It's not yours anymore once it's public. It's like saying "when I do something crazy in public I want to be able to make everyone forget about it later on". That's not how things are supposed to work.
> I don't want anyone to be able to read it anymore
People can still have local copies so you have absolutely NO CONTROL.
