I asked the same question in support channel... It would be nice to hear some official reply.

It's just a pack, such as the Chinese New Year pack or the 4th of July pack, or many other holiday packs.

Plarium is a Ukrainian company and so we occasionally see packs based on their holidays too. :)

My thought is clear.  Any advertisement that donated money would clearly say so. An individual philanthropist may remain anonymous, but would still maki it clear where the money was going.  But when it comes to corporations for profit, only an idiot would have a legitimate promotion donating to a cause and not clearly and explicitly capitalize on it.

Think about it.  In the  past they have done US independence day sales. Did they give any money to the United States? No, they just said celebrate independence.

Annnnd closed. Plarium can celebrate whatever holidays from their own country that they want to. End of story.
