I expect that Wizards staff are aware of the apparently-internal response that the twitterer is criticizing.An anonymous Twitter account calls out WotC for a "tone deaf" response, that no one apparently has seen, and the Twitter account doesn't actually make public if it was an internal memo.
If a large number of WOTC staff do protest tomorrow, I would accept that as a sign that they share rhe author’s concern about WOTC’s response.
