Another entirely speculative suggestion…
Modern culture now seemingly driven by “identity politics” and all the related oddities … Is there a chance that some within club (with their corporate citizen hats on) are advancing an argument that actively supporting and enticing a chant of “red army” might in some way be offensive to some section of society due to its association with military action and its implicit support of the “white patriarchy.”
It could be that it's upset someone somehow but it's unlikely that the club have just come up with a perceived issue imo. If this is the reason there will have been some sort of complaint, which would explain radio silence because explaining the issue would potentially put some third party in the firing line.
