Ventilators weren't as needed as originally thought. USA even killed a lot of patients by being over eager putting them into ventilators. If you put a healthy person in a ventilator there are a few percent chance of giving them pneumonia which typically kills them. When you blast air into their lungs it is really easy to accidentally blast bacteria all over them as well. The articles about "we now know better how to treat patients" was mostly this, don't put them on ventilators unless it gets super critical, most patients got better without one. Also I haven't seen data on this but I strongly suspect the main reason USA lost so many young people to covid compared to other countries is that USA is way more eager to put people on treatment like ventilators, basically blasting bacteria into the lungs of young otherwise mostly healthy people killing them. Those young lives would have been saved if they weren't diagnosed in the first place.
