It is well known that Patriarch Kyrill and numerous other clergy of the Moscow Patriarch openly support Putin and the war against Ukraine. Russian Orthodox clergy have been suspended and even removed for refusing to read the patriarch’s statements supporting Putin and the war.
It is also well known that some in the MP work for Russian intelligence. I have friends originally from Eastern Europe who often complain about the damage that this does to Orthodoxy, and to Christianity in general. So, while I don’t have any firsthand knowledge of what’s going on in Sweden, I find the article you linked entirely believable.
I will also add that the patriarch remains upset that a large number of Orthodox parishes in Ukraine have switched their allegiance from Moscow to another Orthodox jurisdiction.
