The author says paywalls are not the problem but as a reader I don't understand why the autors have to ask for those high prices. The articles you can find in Medium are well written but they aren't scientific articles, with a lot of resourses and time invested to find some data. And the way I find those articles are more like a coincidence than a specific search for economic purposes. I think internet is changing abruptly because of an unsustainable ambition, we are turning all interactions into transactions.
