Yes, they sent me this:
"Dear user,
Thank you for your inquiry. Oracle has withdrawn all operations in Russian Federation and Belarus, hence your account has been de-activated.
You may refer to https://www.oracle.com/corporate/conflict-in-ukraine/russia/.
"
but when I wrote to them that I live in the Czech Republic, they asked me to send confirmation and then they just disappeared:
"Dear user, Please provide any Government address and identity proof."
