All PII (personally identifiable information) of EU/EEA citisens and residents would have to be filtered out, yes.

Chat messages in themselves are not necessarily PII, but then again WhatsApp isn't claiming to freely read the messages. I suppose the messages in the chat could be mined for keywords to give ads to the non-EU/EEA persons.

In theory those messages are E2EE so they don't have access to them anyway.

The same is not true for all the metadata.
