And by all accounts it still has the same c-suite/management structure as before.

This "restructuring" was done in part to protect the whole when all the antitrust shit finally starts to roost. I'll give their lawyers credit here, they foresaw the inevitability getting slammed with antitrust lawsuits, and now they can less painfully peel off the "offending" subsidiaries and blame them for any wrong doing instead of parent meta.

Plot twist: It's totally still meta that's dictating the evil, they aren't fooling anyone, fuck their plausible deniability.
