What do you mean by this? Wikipedia actively encourages people to use archive.is links in citations:

It's not that difficult.
The idea that the permanent record of the internet could hinge on the ethics of one stranger behind a server rack is deeply unsettling.
Knowing the current owner of archive.is doesn't help; we need more full, independent Internet mirrors that can be compared against each other.

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.
I always assumed it was officially sanctioned by the Israeli government, for some unspecified (but almost certainly nefarious) purpose.
My main use for archive.is is for sites that somehow cannot be archived (a message will show up mentioning this site cannot be archive or something along these lines).
archive.is is generally pretty good in forcibly attempting to get an archive, if the HTML doesn't work, the screenshot will work fine. Although archive.is doesn't seem to handle gifs/videos.
They respected exclusion requests after they stopped to respect robots.txt. I don't know their policy for new exclusion requests.
Or they're worried about the paywall by-passing functionality (which is probably what a good portion of people use it for) and copyright claims against archive.today potentially having it taken down and thus breaking a lot of links.
Last I checked, they had archive.is blacklisted; the people with power there had (as far as I can tell) come to the conclusion that people using that site to prove that websites had stated X on date Y were the bad guys. Of course, they still have archive.org sources everywhere, so the objection is not actually to archiving page content.
Tons of claims also seem to be sourced ultimately to thinly-disguised promotional material (e.g. claims of the prevalence of a problem backed up by the sites of companies offering products to combat the problem) and opinion pieces that happen to mention an objective (but not verified) claim in passing.
