We‘re obviously big supporters of the public domain here at Techdirt, and frankly, believe that many more works should be in the public domain. In fact, we treat our own articles, written by staffers here, to be public domain, even though there‘s no official legal mechanism to officially put them in the public domain. We can only proactively state that we will treat them as such. And, of course, thanks to the switch from „opt-in“ copyright to „everything eligible is automatically covered by copyright“ in 1976, combined with ever-farther-reaching copyright term extension, nothing has officially entered the public domain in the US in ages.
