Putting such a message on the crypto wallet is ...at least strange, whatever the situation is. Leaving the community without a downloadable wallet core is something else.
Anyway, how understandable it may be, taking sides utilizing the wallet app splashing politically sided messages against users' faces is somewhat against all principles of why I've been playing with cryptos, trustless, neutrality, permissionless, privacy, etc. The only such message that fits is the message asking for donations for the dev team for maintaining the app or just to thank them for the effort in creating the app.
