according to a Russian Telegram channel
Western journalism is getting increasingly lazy. Reposting speculation with no evidence to back it up, really?
Your quote is not in the article. Here's the only instance of the word "Telegram" in the article:
The cross-border flight was presented as an accident by Russian blogger Fighterbomber, who runs a Telegram channel with close links to Russia’s air force.
Unfortunately, The Guardian doesn't bother to list a single source at all. That's certainly lazy. I didn't dig too deep, but the only reference to a source that I could find anywhere with relation to this story was "a high ranking Ukrainian military official". Not exactly a reliable, unbiased source.
It's right that random channels without verification are not good news but the (accidental) use of empty polarization rhetoric hides good intentions and truth and readers will focus on that
I would demand a medium sized enterprise or two from the privatization website in exchange for defection
