Fear of retaliation may be why many doctors did not go on the record in recent weeks about equipment shortages.

Judge as of 2020-03-28. The claim is strongly hedged ('may be'), so it asserts only a plausible explanation, backed by evidence available by that date. TRUE: by about 2020-03-28, credible reporting documented US doctors or other clinicians being threatened, disciplined or fired, or fearing retaliation, for speaking publicly about equipment or PPE shortages, including clinicians citing fear of retaliation as a reason for staying anonymous. MOSTLY TRUE: such reporting existed but was limited (a few cases), or covered nurses more than doctors. MIXED: retaliation fears were reported, but contemporaneous evidence points mainly to other reasons for anonymity (e.g. hospital media policies without fear of reprisal). MOSTLY FALSE: such reports appeared only after 2020-03-28, or the premise is wrong (doctors were widely speaking on the record by then). FALSE: the evidence shows clinicians were not deterred by retaliation fears and no retaliation threats were reported.

   “many of whom requested anonymity because they did not have permission from their hospitals to speak with the media”

Medscape reported on 2020-03-25 that a surgeon in a Northeast COVID-19 hot spot spoke on condition of anonymity for fear of employer retribution (E1). The same article quoted a physician advocate saying hospitals' silencing of doctors about PPE shortages had become widespread (E2). Vox reported that clinicians asked for anonymity because they did not have hospital permission to speak to the media (E4), and Phoenix New Times reported threats of discipline over PPE use (E3). Together, this reporting from before the claim date meets the TRUE criterion: credible sources described doctors fearing retaliation for speaking publicly about equipment shortages.
