The way I understood it, the questions determined that Facebook didn't even try to gather the evidence they were required to. Saying "we didn't want to do that because it is hard" may fly when they know how hard it is. But they don't even know that! Institutionally incapable because nobody pays for it, they argued.

So why would Meta send someone to explain who doesnt have the capacity to answer those questions? At best they sent the wrong person on accident or they couldnt send the right people for some unknown reason. More likely, they send people with limited knowledge and tell them to only answer questions about areas they are 100% certain about.

If Meta actually wanted to answer they could have 25 people in this room with all the answers. But they dont want to actually answer this question.

Or maybe just implying that Meta isn't up for the task of complying with GDPR, and lack the necessary ability to comply with regulations.
