Best way to "punish" Meta is to slash the Gordian knot and abolish copyright. Level the playing field, incrementally, for everyone else who isn't a trillion-dollar corporation.

The alternative is a futile legalistic attack against a monopoly entity too powerful to be meaningfully punished. That won't accomplish anything useful. It would, rather, help cement this status quo, where copyright infringement is selectively legal or illegal, for different entities at the same time; and companies like Meta thrive arbitraging that difference. You can't defeat Meta—but you can help dig them a moat.
