Somehow, I can just see that happening before our eyes...
Could you imagine if a corporation DID buy out ALL the Internet? I don't just mean buying out YouTube or Napster, but actually having an incredibly powerful reign of control over all the site-creating services (like FreeWebs) and being able to fully filter out/censor/destroy what they like on OUR own webpages...
It would be truly a revolutionary change for the worse. The inevitable removal of the common fansite (due to 'copyright concerns') would be nothing more than a cruel reminder of one of humanity's greatest follies: to let the corporations FULLY and TOTALLY rule over all means of expression on the Internet.
Call it sensationalism or alarmism, but I honestly feel something might happen like it someday. And we'll all be sitting here, leafing through page through page of websites that once were a viable means of expression of the love we held for the shows we feel a deep respect and admiration for.
