They’re accused, not whistleblowers. They can’t retroactively gain the right to anonymity, since their identities have already been revealed.
They could argue that they became whistleblowers as well, and so they should be retroactively anonymized, but that would interfere with the first whistleblowing accusation (there is no point in whistleblowing against anonymous people), and also they’re (I assume) in a position of comparative power here.
There could be a second whistleblowing accusation made by them (but this time anonymously) against the (this time) deanonymized accuser, but given their (I assume) higher social power, that doesn’t seem appropriate.
