If he’s trying to say “Biden wanted this but Trump already started it”

Which “he?”

Zuckerberg blames it exclusively and entirely on the Biden administration.

that tells me BOTH parties requested it. Hence, if you don’t like Biden because of this, you don’t want Trump either. And of course, vice versa. In short, this policy is not unique to either party or administration.

Exactly, but that’s explicitly not what Zuckerberg is saying. He’s saying that it was entirely and exclusively Biden, which is a lie.
