A lot of unsavory people are making sleazy money off of this war for doing very little.
As other have noted, Ukraine is seeking English speaking pilots now. What are the chances that Denys Davydov will heed the patriotic call to return and train to fly the F-16s to defeat the Russians? I wager his "content creation" from Switzerland will continue.
Yes, I suspect that his content creation gig is much more lucrative and cushier than serving his country would be.
