Prolonged ventilation is damaging to the lungs. But ventilation is not given lightly - usually it is for an acute deterioration and is life saving (ie without it, patient would have died in that instance).
Interestingly in COVID it appears that positioning and CPAP/BIPAP can be more effective that venting in edge cases. This is a very new phenomenon in medicine, and we probably over vented in the early course of the pandemic. We were acting in what we knew of other severe respiratory diseases, and the case data from COVID hadn’t had enough time to present best treatment modalities.
However, to suggest that the lungs are not being absolutely ravaged by the virus infecting, replicating and rupturing lung cells is ludicrous
