The video poster, Janne Hukkinen, is indeed in Finland, and has posted this video lecture by Martti J Kari, who passed away this last August (17 November 1960 -- 30 August 2023). Here is his death notice: https://yle.fi/a/74-20047719
One finds from the YouTube link that this particular video has to date " 634 views Oct 31, 2022 JYVÄSKYLÄ UNIVERSITY."
In terms of those channels marketing, the YouTube page of Janne Hukkinen shows: "The channel author is a participant in the Amazon Services LLC Associates Program, An affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com -- FTC Disclosure Statement: Some links on this youtube channel may be affiliate links. We may get paid if you buy something or take an action after clicking one of these."
So, a "cottage industry" is observed. Money. But to be fair, Kari's PhD thesis is available.
Looking at Janne Hukkinen posted videos, she seems somewhat new to war reporting, YouTube style, Hukkinen beginning the reporting about a year ago, halfway into this conflict. Joining the "click, donate, support" stratagem.
What was also interesting was your seemingly anomalous AdmSmith link:
https://freerepublic.com/focus/news/4042550/posts?page=5655#5655Much "AdmSmith to AdmSmith" with over 5600 comments to self, likely as a journal of Free Republic posts about the Ukraine-Russia war. Using Free Republic as a repository of comments posted to one's self, one supposes?
Janne Hukkinen is a male and he made the video version, originally in Finnish, to learn automatic translation etc.

There are more videos with Kari, but they are in Finnish.
What I write on FR is a by-product of other things I do.
