The original title was a bland thing conveying naught but the thin idea that the world changes. A better objection is that the submitted title does not accurately reflect what is clearly Marlinspikes thesis statement:
> "I no longer believe that it is possible to build a competitive federated messenger at all"
Personally I think the new titles stays pretty close to the thesis statement, but it might be a bit exaggerated as clearly Marlinspike doesn't mean "technically impossible" but rather something more like "socially unworkable".
