The Lancet report also indicates 'no stimulation' is a possible 'sham stimulation,' whereas, in my estimation, 'sham stimulation' means stimulation other than 'no stimulation' or 'intended stimulation.' Its possible the complete absence of stimulation might be harmful in the presence of the implants because the implants may, in effect, cause short-circuits and thus increase the energy neurons must produce to sufficiently activation the synapse. The change in stress neurons may undergo might increase their load and thereby possibly reduce the neuron's longevity. A stimulation offsetting this effect ought to be possible - if it is needed.

The limited amount of French comment on the studies might in fact only be in reference to the Lancet report and thus the remarks implying the French study encountered trouble too is possibly only a rumor.
