The game is indeed a clean example of Glomarization.
I might have misunderstood your main point, which I interpret as: “because of the counterfactual that I could have gotten a high card in this game, I shouldn’t reveal a low card with probability 1.” Are you sure that it’s because of the counterfactual in the current game, and not the possible consequences in my later interactions with B?
I would reveal my card if the game was truly unique, in that zero information leaks out. (Suppose B’s memories of this game are erased afterwards.)
In real life, my decision would affect Player B’s image of me, which affects how he will reason about similar games against me in the future. (And even how people close to him will reason about people like me.)
A multi-agent influence diagram on the iterated version shows how one can screw himself over in later games. If A first hides, then B cannot update her model of A:
If A first reveals a low card, then a pattern that’s almost-but-not-quite-like Newcomb’s is revealed:
The linked website for military assistance (war.ukraine.ua) is dubious. Donations in fiat currencies are better done at the addresses listed on the official website: https://bank.gov.ua/en/about/support-the-armed-forces
Couple telltale signs:
ukraine.ua redirects to war.ukraine.ua, which is weird in itself, but especially given in January there was some original content at ukraine.ua
email listed in the footer is ukraine.ua.mfa@gmail.com, despite the mfa.gov.ua accepting emails at zsmfa@mfa.gov.ua
their https://war.ukraine.ua/support-ukraine/ page lists yet another Gmail address (mfa.ukraine@gmail.com)
the Feb 28 archived version showed ukraine@mfa.gov.ua email
one IBAN does check out (although bank.gov.ua lists this as UAH only and lists seven others for different currencies), but the others aren’t mentioned on the bank.gov.ua website
the Monobank payment (https://uahelp.monobank.ua/) uses a British bank “Clear Junction Limited” for the euro transfers instead of Deutsche Bundesbank or a Ukrainian bank.

This @Ukraine user posts mostly memes and low-effort posts lately. On Feb 26 they listed a different bitcoin address but now I can’t find the post.
