What if they had named Facebook in that list, and then Facebook became Meta?

I don't know anything about the legal side of things, but although I can see the appeal of a short blacklist, I think it would be a can of worms.

Most of the Facebook companies are still called Facebook, see for example FACEBOOK IRELAND HOLDINGS UNLIMITED COMPANY https://opencorporates.com/companies/ie/466405 and some of its connected companies.

Still, you'd probably need a license steward to keep the list of companies up to date, and you'd keep the list in an annex. Alternatively you'd need to pick some objective thresholds, such as "more than 1 T$ market cap or more than 100 G$ global annual revenues". This is the approach the EU followed with the Digital Markets Act.

(I'm not saying that I'm endorsing such an approach.)
