> What you are saying is equivalent to stating a tautology: Elsevier is still important for researchers' careers because Elsevier is still important for researchers' careers.
It appears you've entirely missed the point. There is no tautology. There is only a vicious circle of being forced to publish in established journals to have a chance of having or even starting a career in research, and the fact that most if not all established journals are controlled by companies such as Elsevier. Therefore if your chances of having a career depend on consuming a service sold by the likes of Elsevier and producing content for Elsevier, it's quite obvious that you have to play along this scheme if you intend to have a career.
