I never concluded that but this actually allows someone, the anonymous here to change the history/info backwards if needed. For russians as an example this would be powerfull tool to manipulate narrative, which is cultural there at this point. Pretty smart and dangerous if it is really operated by them.
Ignoring the fact that one of this service's primary reason for existing is that corporations and governments are already abusing their ability to retroactively change history.
If this is truly a concern then the answer is to have more than one publicly-accessible independent archive service. Archivebro has never taken any steps towards securing a monopoly on archiving things. The FBI are the only ones doing that.
Also not everybody in Russia is on the FSB payroll. News media always stops investigating as soon as there is credible information that somebody or their server is located in Russia because if they learn too much then it becomes difficult to discredit them as "possibly being linked to the kremlin". If you used any other nationality to imply that somebody is acting in bad faith on behalf of a hostile foreign government without additional evidence those same journos would call you a racist and try to get you canceled.
