It is valid for them to make sure accounts cannot be taken over by hostile actors, and it is valid for them to assume that you are able to notify them about email address changes in time.
Tell me, how many years did you have to resolve the situation regarding your email address before it came to this?

No and it is shitty to implement this new authentication system after all these years, however should they just hand over any account to some rando writing an angry email? If that were the case, we’d be reading about that right now (“Rockstar gave my account away!”) instead of this.
