In case someone takes this as actual advice, I think this comment is best accompanied with a warning that this gets them to call a lawyer for sure ^^'

(OP mentions a lawyer in the title, but the post only speaks of a data protection officer, which is a very different role and doesn't even represent the organization's interests but, instead, the users', at least under GDPR where I'm from)
