It is very simple, i have to publish if i want to get my phd. And due to years of corruption those publications have to be in certain journals.
My work isnt financed by the publishers. Neither is the review process, my doctoral supervisor gets nothing out of doing reviews like these. I also pay to attend the conference, which is mandatory to get published.
I am coerced into signing away my (publicly funded) research to then see it put behind a pay wall. Preventing me from sharing it freely robbing me of the feedback from my peers.
Elsevier are a cancer and only function through forced labor. Not only are they rentseeking on somebody elses work, they are creating a worse situation for everyone involved. Including Science itself.
