He renamed his company Meta, as in metaverse.

I understand you are responding to the 'always', but can we agree that at least his level of confidence in an idea isn't a great indicator?

He bought those after they were already big. He can claim Facebook obviously, but not much else.

He bought those, they were not built by meta.

Talking about original ideas/ip.

Isn’t the definition of last mover that it isn’t an original idea?

Managing his own companies with copies of ideas hasn't gone very well for him AFA I remember, acquiring companies that are good in their field and not ruining them has been a talent compared to other Techs.

They weren't last movers in both examples. They had a product, it failed to get a userbase... they bought the users.
