All knowledge should not be free. The comment above mine wrote knowledge should be free and easily accessible. They are talking about all knowledge, not just academic journals, and that makes no sense.
They did not say information should be unfunded or creators demonitized. They said information should be "free" as in liberated, as in freedom.
Valuable information is virtually costless to copy and yet you can be locked away in a cage by men with guns for accessing it. It's not far off from how North Korea handles people found with Western media. That's what the commenter above is advocating against.
Have some perspective.
Have a moment of self awareness for one second and consider this: if I had to make the same rebuttal multiple times to counter act the same argument then who is the spammer and who is just setting the record straight? Hmmmm
