Perhaps, and yet I've referenced this article numerous times over the years. The most important property of an archive is that it saves an authentic copy of the source material—that is to say, the archive must be trusted. If archive.today is indeed a legitimate archival source first and foremost as it purports to be, the user has a reasonable interest in investigating the people behind it so that they can come to an informed conclusion about if they can trust the archive or not.

There are different scenarios and different needs. Trust-wise, the enemy of your enemy may be your friend. Dodging legal liability can be an asset too, if you are dealing with evidence against the government, or powerful people within your jurisdiction. Wikileaks fills a similar role. And archive.org certainly isn't trustworthy with respect to US political influence. They are trying to rewrite history, they will purge the archives, too.

For the average case, you shouldn't fully trust any one service IMO.

BTW, there is a neat browser add-on, which lets you search across various archives: https://github.com/dessant/web-archives
