I hate this so bad. You know that the solution will be that EU will block US companies (who do not comply) so EU users will eventually get their own WhatsApp called MsgMeNow. The result is that nobody can talk to people outside their own jurisdiction.
This is effectively what we see in China. They only use WeChat, I was unable to register because it says I need someone to verify my account when I try to do it (this has been happening since 2018)
