but we can't say that for sure? we don't know how many votes were cast by each country in ROW so not being in the top 10 countries from row (of over 100) =/= they have no interest
I think you actually can. I‘m not denying there might be an interest but it definitively is - as proven by the figures now - far far less important that some proponents (including the Kazhak officials) pretended.
And it aligns with an Interview with the founder and owner of the only broader known fansite esckaz.com, who is btw russian - not kazhak. (as is the whole site). The interview was led by one of the better known german and austrian bloggers Mario Lackner and Oliver Rau and can be read in their book „Friede Freude Quotenbringer“. There „Andy“ (= Andrey Mikheev) tells how he got to create esckaz.com. I freely translate:
„I worked as webmaster for the biggest festival of Asia
Voice of Asia. It took place in Alma Ata / Kazhakstan and while flipping through the biographies of the contestants, I noticed that an event called „Eurovision“ was emerging several times: with Claudette Pace, Fabrizio Faniello, Monica Anghel,…
(…)
After having read about Eurovision, I wanted to know as much as I could about the event. In Russian this was doomed - there was absolutely nothing to find about the Eurovision song contest. So I decided to start my own site as a source of information in russian for all those who are interested in the ESC“
So the only known alledgedly kazhak fan website is made my a russian to inform in russian about almost exclusively ex-soviet countries. Also the rest of the team of the site (which btw has not been updated since 2020) is not from Kazhakstan but from Russia, Latvia and 2 correspondants from the UK. And it doesn‘t even have a section about Kazhakstan.
I just made a google search with the options „ESC eurovision song contest“ and limited it to the country of Kazhakstan. Do you know how many relevant hits I got? 13 (in words thirteen). And most of them news sites, that mentioned JESC. Not a single one identifiable as a fansite.
Now what is more probable in the light of this: that Kazhakstan has a huge fanbase who somehow does not massively vote once they have a chance to do so or that the interest is actually rather a minor one?
I logically would tend to believe the latter , but you free to differ of course.
