That page says that "net income" message the sense you meant it and "gross income" means the sense I understood it.

It does say that unqualified "income" means the net version but it's a push to say that makes it unambiguous. (And, at I said on a sibling comment, this seems to be a US convention.)

Meta is a US company and Reich is a US citizen offering commentary on US domestic policy. "Income" is unambiguously net income in the US.
