We show how the recent computer simulation data reported by Caracciolo et al. for the three-dimensional $\pm$ J Ising spin glass in a uniform magnetic field are, in contrast to their claims, quite consistent with the simple scaling or droplet theory developed by McMillan, Fisher and Huse, and Bray and Moore, and do not provide evidence for a de Almeida-Thouless transition.
